Question

Frankie is saving for a new game system that costs $499. His savings account currently holds $150. He plans to deposit $10 a week into the savings account until he has enough to buy the game system.

In how many weeks will Frankie be able to purchase the game system?

Answer 1

35 weeks

Explanation:

If Frankie already has $150 in his bank account, we can subtract it from the cost of the game.

$499 - $150 = $349

Now we can begin to solve for the number of weeks it will take for Frankie to purchase the game system.

If he needs $349, and he adds $10 every week,

10 weeks would give him $100

5 weeks would give him $50

$100 + $100 + $100 + $50 = $350

10 + 10 + 10 + 5 = 35

It would take Frankie 35 weeks to be able to buy the game system.
