conversations.value: Sandra wants to buy some sweets. She saved $10 for this purpose. Her mother gave her an additional $4, and her father twice as much as her mother. One candy costs $0.5, and one jelly bean $0.2. She wants to buy 14 candies and 20 jelly beans. How much money will she be left with after the purchase?
  Work out the solution step by step.
conversations.from: assistant
conversations.value: Sandra's father gave her $4 * 2 = $8.
  So Sandra has in total $8 + $4 + $10 = $22.
  She wants 14 candies, so she is going to pay 14 candies * $0.50/candy = $7 for them.
  She wants also 20 jellybeans, and they're going to cost 20 jellybeans * $0.20/jellybean = $4.
  So after the purchase, she will be left with $22 - $4 - $7 = $11.
