Question

Maria started an account with an initial deposit of $47.00 on week 1. She then deposited $18.50 into the account each week thereafter for a total of 40 weeks. How much was the balance of the account after 40 weeks?

Answer 1

$121.00

Explanation:

y = 18.50x + 47.00

y = the total amount in the account

x = the number of weeks

y = 18.50(4) + 47.00

y = 74.00 + 47.00

y = 121
