Whom do price supports benefit and whom do they hurt?

Maria is a hard-working college sophomore. One Sunday, she decides to work nonstop until she has answered 100 practice problems

sdas [7]

Answer:

The correct answers are:

i. The marginal, or additional, gain from Maria’s first hour of work, from 8:00 AM to 9:00 AM, is 40 problems.

ii. The marginal gain from Maria’s third hour of work, from 10:00 AM to 11:00 AM, is 20 problems

iii. 2 hours working on problems, 2 hours reading (c)

Explanation:

i. The marginal gain from 8:00 AM to 9:00 AM is calculated thus:

work done at 8:00 AM = 0 problems

Work done at 9:00 AM = 40 problems

Marginal gain = (Work done at 9:00 AM) - (work done at 8:00) = 40 - 0 = 40 problems

ii. work done at 10:00 AM = 70 problems

work done at 11:00 AM = 90 problems

Marginal gain = 90 - 70 = 20 problems

iii. To get the best exam score, the most number of problems possible in total must be answered within the 4-hour period, and this is determined as follows:

we are told that Maria gets tired as time progresses and the number of questions answered reduces we notice the following numbers of questions answered in each hour:

8:00 AM to 9:00 AM = 40 - 0 = 40 problems (hour 1)

9:00 AM to 10:00 AM = 70 - 40 = 30 problems (hour 2)

10:00 AM to 11:00 AM = 90 - 70 = 20 problems (hour 3)

11:00 AM to Noon = 100 - 90 = 10 problems (hour 4)

Also, we are told that;

1 hour of reading = 25 problems

Comparing the reading and solving problems, we see that the number of problems solved in hour-1 and hour-2 (40 and 30 respectively) are more than the equivalent number of problems solved in reading for 1 hour, while hour-3 and hour-4 (20 and 10 respectively), have lesser equivalent number of problems each, than reading for one hour. Therefore to make the most out of the 4 hours, Maria will spend the first 2 hours solving problems and the next two hours reading, giving a total of: 40 + 30 + 25 + 25 = 120 problems solved.

Mankus Inc. is considering using stocks of an old raw material in a special project. The special project would require all 120 k

Digiron [165]

Answer:

$760

Explanation:

The computation of the relevant cost is shown below:

= Discounted price per kilogram × number of kilograms - delivery cost

= $6.75 × 120 kilograms - $50

= $810 - $50

= $760

The delivery cost is already involved in the total cost. So, we have to deduct it to find out accurate relevant cost . The other information which is given is not relevant. So, we ignored it

Today, you borrowed $3,200 on a credit card that charges an interest rate of 12.9 percent, compounded monthly. How long will it

miskamm [114]

Answer:

It will take me = 30.99 years to pay-off the borrowed amount paying $60.00 every month

Explanation:

SOLUTION:

Using the Formula: A = P(1+r/n) ${nt}$

Where:

A= $60.00;

P = $3,200.00;

r = 12.9%;

n = 12

t =?

Substituting the values into the Formula =

$60 = $3,200(1 + 12.9%/12) ${12t}$

= $60 = $3,200(1 + 12.9%/12) ${12t}$

= $60.00 = $3,200.00 (1 + 0.129/12) ${12t}$

= $60.00 = $3,200.00 (1 + 0.01075 ) ${12t}$

= $60.00 = $3,200.00 (1.01075 ) ${12t}$

= $60.00/$3,200.00 = $3,200.00 (1.01075 ) ${12t}$ /$3200.00

= 0.01875 = (1.01075) $12t$

= Using the law of logarithm

= log $A^{N}$ = Nlog A

=12tlog(1.01075) = log0.01875

= 12log(1.01075)/(1.01075) = log0.01875/log(1.01075)

= 12t = log(0.01875)/log1.01075

= 12t = 1.7270/0.04644

Divide 12 by both sides

=12t/12 = 371.88774/12

t= 30.9898

∴ 30.99 years

It will take me = 30.99 years to pay-off the borrowed amount paying $60.00 every month
