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