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.
