Lisa took out a loan for 5 months and was charged simple interest at an annual rate of 4.8%.
denis-greek [22]

Answer:

<em>Lisa borrowed $8,500</em>

Step-by-step explanation:

<u>Simple Interest </u>

Occurs when the interest is calculated on the original principal of a loan only.

Unlike compound interest where the interest earned in the compounding periods is added to the old principal, simple interest only considers the principal to calculate the interest.

The interest earned is calculated as follows:

I=Prt

Where:

I = Interest

P = initial principal balance

r = interest rate

t = time

Lisa took out a loan for t=5 months and was charged simple interest at an annual rate of r=4.8% = 0.048. She paid interest for I=$170.

We need to convert the time to years (there are 12 months per year):

t = 5 /12 years.

The formula must be solved for P:

\displaystyle P=\frac{I}{rt}

Substituting:

\displaystyle P=\frac{170}{0.048*5/12}

\displaystyle P=\frac{170}{0.02}=8,500

Lisa borrowed $8,500

g100num [7]

Answer:

Bag 2

Step-by-step explanation:

Given

Bag 1:

14\ ounce = 3.50

Bag 2:

24\ ounce = 5.28

Required

Which is a better buy

To get which buy is better, we first get the unit price of each bag.

Unit\ Price = Amount/Size

For bag 1:

Unit\ Price = 3.50/14

Unit\ Price = 0.25

For bag 2:

Unit\ Price = 5.28/24

Unit\ Price = 0.22

The best buy is the one with smaller unit price

Hence, bag 2 is better to buy

<h3>Problems with validity.</h3>

It should be noted that in a research, a problem with validity takes place when there's a lack of reliability of the independent variable.

Also, it is a result of lack of representativeness of the independent variable and a lack of impact of the independent variable.

In this case, the researcher sets out to measure drug use on US college campuses by asking a representative sample of undergraduates whether they are currently receiving federal grants or loans. It should be noted that the question asked doesn't relate to the research.

In conclusion, there's a problem with validity.
