Question

Tom is planning a party for five friends at a game arcade. He can buy different numbers of game tokens for the prices shown on the table

each friend will have 25 game tokens.

how much money could tom save, in dollars, if he buys all 125 tokens before the party rather than separately as each friends arrive?

Answer 1

He can save 20 dollars

Explanation:

He can buy one 100 token amount and one 25 token amount. This will cost 20 + 10 dollars, or 30 dollars. If each friend buys 25 tokens, it will cost

10 * 5 dollars, or 50 dollars. 50 - 30 = 20. So he can save 20 dollars.
