<human>:  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?
<bot>: How much will the cassette tapes cost? ** The cassette tapes will cost 2 × 9 = $<<2*9=18>>18.
How much money does Josie spend? ** She spends 18 + 25 = $<<18+25=43>>43 in total.
How much money will Josie have left? ** Josie will have 50 - 43 = $<<50-43=7>>7 left.
