conversations.value: I'm stuck on this math problem: A snack machine accepts only quarters. Candy bars cost ¢25, each piece of chocolate costs ¢75, and a pack of juice costs ¢50. How many quarters are needed to buy three candy bars, two pieces of chocolate, and one pack of juice?
  Can you help?

conversations.value: Three candy bars cost ¢25 x 3 = ¢75.
  Two pieces of chocolate cost ¢75 x 2 = ¢150.
  So, the total amount needed to buy those is ¢75 + ¢150 + ¢50 = ¢275.
  Since a quarter is equal to ¢25, therefore ¢275/¢25 = 11 quarters are needed.
