Hope this helps :)

Answer 2

Answer:  306 dollars

===========================================

Work Shown:

i = P*r*t ..... simple interest formula

i = 300*0.02*1

i = 6

Your brother pays $6 in simple interest on top of the $300 in principal loaned to him. The total amount he pays back is 300+6 = 306 dollars.

----------

Another way to calculate the answer is to do these steps

A = P*(1+r*t)

A = 300*(1+0.02*1)

A = 300*(1.02)

A = 306

The 1.02 represents a 2% increase when going from 300 to 306.
