conversations.value: I would love to understand how to solve this problem: Gus spent $20.00 at the grocery store.  He bought 2 bag of chips for $2.00 each, a bucket of fried chicken for $8.00 and a bottle of soda for $1.00.  How much did the apple pie cost?
  Can you explain?

conversations.value: He bought 2 bags of chips at $2.00 each so they cost 2*2 = $4.00
  He spent $4.00 on chips, $8.00 on fried chicken and $1.00 on soda so he spent 4+8+1 = $13.00
  He spent $20.00 and all of the groceries, except for the pie cost $13.00 so that means the apple pie cost 20-13 = $7.00
