Finding the balance of an account with simple interest

Question

I have two questions and I have to find the balance.

 

1.  $200 at 3% for 5 years

 

2.  $750 at 8% for 5 years

Answer 1

i = prt

i = 200(.03)(5)

i = $30

Balance = 200 + 30 = $230

 

i = prt

i = 750(.08)(5)

i = $300

Balance = 300 + 750 = $1050
