Answer:

$190.77

Explanation:

Given that:

Actual purchase price = $175

Sales tax = 7.75%

Total = actual price + sales tax

Total = actual sales price + (7.75% * Actual sales price)

Total = $175 + (0.0775 * $175)

Total = $188.5625

To pay with credit card at 0.039% daily interest for 30 days :

(188.5625 * 0.039% * 30) + 188.5625

2.20618125 + 188.5625

= $190.76868125

= $190.77

OverLord2011 [107]

Answer:

  • The marginal gain from Larry's second hour of work is 60 problems
  • The marginal gain from Larry's fourth hour of work is 20 problems
  • The best combination is 1 hour of working problems + 3 hours of reading

Explanation:

To get the <em><u>marginal gain</u></em> we subtract from the latest hour, in this case the second hour (140), the production from the previous hour (80). 140-80=60. <em>It's always the same, the latest minus the previous one.</em>

So let's do the same for the fourth hour:

Noon................200 problems

minus

11:00 AM..........180 problems

200-180= 20 problems

Now to know how many hours he should spend working on problems and reading, let's compare:

An hour of reading equals to 70 problems made; (because working on 70 problems raises a student’s exam score by about the same amount as reading the textbook for 1 hour).

hours of working problems         problems solved

0............................................................0

1.............................................................80

2............................................................140

3............................................................180

hours reading                    problems equivalent to hours read

4...............................................(4*70)=280

3...............................................(3*70)=210

2...............................................(2*70)=140

1................................................(1*70)=70

finally let's add up the two combinations (0 and 4, 1 and 3, 2 and 2, 3 and 1)

0 and 4_______________0+280= 280

1 and 3________________80+210=290

2 and 2_______________140+140=280

3 and 1________________180+70=250

<em>And the best combination is 1 hour of working problems + 3 hours of reading=</em><em>290</em>

Study groups: do they work or not?
Oduvanchick [21]

Answer:

When working on a group project, studying and working within a group will be a necessity, so you need to make it work for you! Studying in groups has its advantages and disadvantages, but the trick is to know when to resort to solo studying and when to go for group studying. Studying with a partner is a valuable way to learn as students help one another at overcoming weak points.

Advantages of Studying in Groups

1. Brainstorming

Studying in groups allows students to share their different thoughts with one another. This notion usually leads to a better learning process, since brainstorming generates new ideas and thus, students learn the same thing but with different perspectives. Open discussion enhances thinking skills and will give you access to others information and as a result, broadens your mind.

2. Clarification Discussions

Students are different and they perceive the same information differently. You can always ask your study mate to clarify a vague point for you and vice versa. Also, this action increases retention and reinforces the ideas, because the more the information is repeated the stronger the memory will be.

3. Motivation Booster

Group studying is the best procrastination solution as it breaks the monotonous learning process and it makes you attentive to what the others are saying. Mock tests and trial quizzes assist those struggling with course materials and those extracting tests and quizzes from them as well.

Disadvantages of Studying in Groups

1. Distraction

The benefits of group studies are a lot but there are also some cons to group studying. You may find it tiresome to stay focused when studying in a group. Sometimes the conversation shifts from studying to trendy events maximizing distraction. Studying alone might be helpful if you need undivided attention to the materials at hand.

2. Lack of Efficiency

Group studying hampers creativity and efficiency and when there are exams on the horizon, efficiency should be the priority. Studying alone will give you time and space to do your personalized studying. Also, when alone, you can focus freely on a certain part because you know you need to and skip other parts that you have already mastered. This allows you to manage your time wisely and prioritise your tasks.

3. Impersonalized Learning

Our brains conceive information differently, and in order to digest information correctly, you have to do it your own way, not another’s. When studying in a group, you might be studying at someone else’s pace, whether it is too fast or too slow, it will not help you with learning. Also, you might lose track of your own questions and the difficulties you might be facing with the subject at hand because students mostly do not want to diverge from the group. Creating personalized study plans for suture references will also save much time if the student loves to follow a plan and a schedule while studying.

Preferring one way over another does not necessarily mean that it is better; however, it simply means that people choose what suits their characters best. For example, a social person might find it difficult to study alone and find it more appealing to talk to people to learn and on the other hand, another social person will choose to study alone because he gets distracted easily with people and he can focus better when alone. In a nutshell, there is no way advantageous than the other; everyone has his own studying methods and each has its advantages and disadvantages.

nikitadnepr [17]

Answer:

Software as a Service (SaaS)

Explanation:

Software as a service (SaaS) allows users connected to cloud-based applications over the Internet and use them. Some common examples are email, calendars and office tools (such as Microsoft Office 365).

SaaS offers a comprehensive software solution that is acquired from a cloud service provider through a pay-per-use model. It is possible to rent the use of an application for the organization and users connect to it through the Internet, usually with a web browser. All underlying infrastructure, middleware, software and application data are located in the provider's data center. The service provider manages the hardware and software and, with the appropriate service contract, will also guarantee the availability and security of the application and data. SaaS allows an organization to get started and can run applications with a minimal initial cost.

After visiting several automobile dealerships, Richard selects the used car he wants. He likes its $11,500 price, but financing
aksik [14]

Explanation:

I = Prt

I = (10000)(.11)(4) = $4400

Total Cost = Down Payment + Principal Borrowed + Interest

Total Cost = 2000 + 8000 + 4400

= $14,400

Monthly Payment = (Principal Borrowed + Total interest) / Total number of payments

Monthly Payment = (10,000 + 4400) / 48

= $300

APR= (2 × n × I) / [P × (N + 1)]

APR = (2 × 12 × 4400) / [10,000 × (48+1)]

= 21.55%
