Lizzy: Barry has $10.00 worth of dimes. His little brother, Dan has half that amount but finds 2 more dimes on his way home from school. How many dimes does Dan have?.
Me: Hmmm, let me think. I think this is the detailed solution:
Dimes are worth $0.10 and Barry has $10.00 worth of dimes so he has 10 / .10 = 100 dimes. Dan has half the amount of dimes as Barry so Dan has 100 / 2 = 50 dimes. Dan finds 2 more dimes on his way home so he now has 50 + 2 = 52 dimes. Final answer: 52.
