conversations.value: 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?
  Give me a solution to this problem

conversations.value: He wants to buy a $60 game and $5 of candy so 60 + 5 = $65
  He will make $8 per hour of babysitting and will work 9 hours so 8 * 9 = $72
  He made $72 and spent $65 so 72-65 = $7 left over
