2. John is thinking about buying a letter jacket for $180.00. Dry cleaning the jacket would cost about $10.00. John estimates he would have the jacket
cleaned six times a year.
How many years could John wear the jacket before cleaning costs would equal the purchase price?

What would his total investment be after this amount of time?
How many times would John have to wear the jacket to make the cost per wear $5.00 or less?
