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?
Faye's mother gave her 2 x $20 = $<T>multiply(2, 20)=40
So, Faye had a total of $20 + $40 = $<T>add(20, 40)=60
Ten cupcakes cost 10 x $1.50 = $<T>multiply(10, 1.5)=15.0
Five boxes of cookies cost 5 x $3 = $<T>multiply(5, 3)=15
Thus, Faye spent $15 + $15 = $<T>add(15, 15)=30
Therefore, Faye has $60 - $30 = $<T>subtract(60, 30)=30 left.
