Question: Faye had $20. Today, her mother gave her twice as much as her money. If she bought ten cupcakes at $1.50 each and five boxes of cookies at $3 per box, how much money did she have left? Think carefully first, then make a decision:
Faye's mother gave her 2 x $20 = $40. So, Faye had a total of $20 + $40 = $60. Ten cupcakes cost 10 x $1.50 = $15. Five boxes of cookies cost 5 x $3 = $15. Thus, Faye spent $15 + $15 = $30. Therefore, Faye has $60 - $30 = $30 left. So the answer is 30.
