Calvin has $360 less in his savings account than he had 8 weeks ago. Each

week he deposited $15 into his account. What was his average withdrawal

each week?

Calvin withdraws $ 60 each week

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Calvin's account balance difference than 8 weeks ago = - $ 360

Weekly amount Calvin deposits = $ 15

Number of weeks to compare = 8

2. What was his average withdrawal each week?

Let's calculate the weekly average withdrawal this way:

Weekly average withdrawal = [Calvin's account balance difference than 8 weeks ago - (Weekly amount Calvin deposits * Number of weeks to compare) ]/Number of weeks to compare

Replacing with the values given:

Weekly average withdrawal = [-360 - (15 * 8) ]/8

Weekly average withdrawal = - 360 - 120 / 8

Weekly average withdrawal = - 480 / 8

Weekly average withdrawal = - 60

Calvin withdraws $ 60 each week
