if Sonja makes $2100 interest after investing $15,000 at 2.8%, how many years did she invest for?

Answer:

Sonja invested for 5 years.

Step-by-step explanation:

First you have to find how much money she gets in one year.

To do this you would have to multiply 15,000 and 2.8.

15,000 x 2.8 = 42000

You move the decimal 2 spaces forward since there are 3 zeros in 15,000 and one decimal place in 2.8.

This gives you 420.

To find how many years it takes for her to make $2100 you have to divide

2,100/420.

This gives you 5, which means that she invested for 5 years.
