Colleen and Jimmy have part-time jobs after school. Both have decided that they want to see how much money they can save
in one semester by placing part of their earnings each week into
a savings account. Colleen currently has $120 in her account and
plans to save $18 each week. Jimmy currently has $64 in his savings
account and plans to save $25 each week.
4. How much money will each person have in his or her savings
account after 18 weeks (the amount of time in one semester)?
