Answer:
$306
Step-by-step explanation:
In one year, the 2% annual interest would have been applied once. Therefore, your brother would pay you 1.02 * 300 which is 306.
Hope this helps :)
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.
It would take her 90 minutes to run 10 miles.
First you should divide 54 by 6 and you'll get 9. So it takes her 9 minutes to run 10 miles (which is physically impossible). You multiply 9 times 10 and get 90.
hope this helps you..
