Chris wanted to buy a new video game that costs $60 as well as an assortment of candy that costs $5.  To earn the money, he agreed to babysit his little sister for $8 per hour.  If he works 9 hours, how much money will be left over after he makes his purchases?
He wants to buy a $60 game and $5 of candy so 60 + 5 = $<T>add(60, 5)=65
He will make $8 per hour of babysitting and will work 9 hours so 8 * 9 = $<T>multiply(8, 9)=72
He made $72 and spent $65 so 72-65 = $<T>subtract(72, 65)=7 left over
