conversations.value: Sarah is buying Christmas presents for her family. She starts her shopping with a certain amount of money. She buys 2 toy cars for $11 each for her sons. She buys a scarf for $10 for her mother. Then she buys a beanie for $14 for her brother. If she has $7 remaining after purchasing the beanie, how much money did she start with?

conversations.value: Before purchasing the beanie, Sarah has $7 + $14 = $21
  Before purchasing the scarf, Sarah has $21 + $10 = $31
  The total cost of the toy cars is 2 * $11 = $22
  Before purchasing the toy cars, Sarah has $31 + $22 = $53
