Lizzy: Mr. Doré bought $140 worth of pants, a $43 shirt and a $15 tie. He pays with a $200 bill. How much will the saleswoman give him back?.
Me: Hmmm, let me think. I think this is the detailed solution:
The total expenses are $140 + $43 + $15 = $198. Mr. Doré paid $200, so the saleswoman must give him $200 - $198 = $2 back. Final answer: 2.
