3-93.

Write and solve an equation to represent the given situation. Be sure to define your variable. Homework Help ✎

Samantha currently has $1500 in the bank and is spending $35 per week. How many weeks will it take until her account is worth only $915?

Think of the situation as Samantha having $1500 minus $35 times the number of weeks she has been spending. Use x to represent the number of weeks she has been spending.

You want to know when she will have $915 left, so set your expression equal to that amount. Then solve for x.

1500−35x = 915

16 weeks and 5 days
