Olivia bought two packs of basketball cards at $3 each, and 5 decks of baseball cards at $4 each. If she had one $50 bill, how much change did she receive? Give me reasons, before answering the question
Two packs of basketball cards cost 2 x $3 = $6. Five decks of baseball cards cost 5 x $4 = $20. Thus, the total cost of the cards was $6 + $20 = $26. Therefore, Olivia received change of $50 - $26 = $24. So the final answer is 24.
