Isabelle has $5250 in her bank account and makes automatic $750 monthly payments on a home loan. Ifshe stops making deposits to that account, when would the automatic payments make the value of theaccount zero?The value of the account would be zero inmonths.

Answer 1

Let's define

x: months

If she stops making deposits and makes automatic $750 monthly, her account would have 5250 - 750x dollars after x months.

To find when the value of the account will be zero, we have to solve:

5250 - 750x = 0

5250 = 750x

5250/750 = x

7 = x

The value of the account would be zero in 7 months.
