conversations.value: Please show me the solution for: A movie theater company is advertising a deal of a movie ticket, a bucket of popcorn, a drink, and a box of candy for $20. Normally, a movie ticket costs $8, a bucket of popcorn costs three dollars less, a drink costs a dollar more than popcorn, and a candy costs half as much as a drink. How many dollars does the deal save a customer who buys a ticket, popcorn, drink, and candy normally?

conversations.value: The popcorn costs 8 - 3 = $5.
  The drink costs 5 + 1 = $6.
  The candy costs 6 / 2 = $3.
  The normal price is 8 + 5 + 6 + 3 = $22.
  Thus, the deal saves a customer 22 - 20 = $2.
