Lizzy: Jay bought a book for $25, a pen for $4, and a ruler for $1. He paid with a fifty-dollar bill. How much change, in dollars, did Jay get?.
Me: Hmmm, let me think. I think this is the detailed solution:
Jay spent 25 + 4 + 1 = 30 dollars. He received 50 - 30 = 20 dollars in change. Final answer: 20.
