Josie received $50 as a gift. She plans to buy two cassette tapes that cost $9 each and a headphone set that costs $25. How much money will she have left?
The cassette tapes will cost 2 × 9 = $<T>multiply(2, 9)=18
She spends 18 + 25 = $<T>add(18, 25)=43 in total.
Josie will have 50 - 43 = $<T>subtract(50, 43)=7 left.
