conversations.value: I would love to understand how to solve this problem: Susie opens a pizza store. She charges $3 per slice and $15 for a whole pizza. If she was able to sell 24 slices of pizza and 3 whole pizzas, how much money did she earn?
  Can you explain?

conversations.value: She was able to earn 24 x 3= $72 after selling 24 slices.
  She earned 15 x 3= $45 after selling 3 whole pizzas.
  Therefore, she earned a total of $72+$45= $117.
