Question

Granola bars cost 45 cents, gum cots 35 cents, and crackers cost 50 cents. Lauren buys two different items. She pays with a 1 dollar bill and receives 3 of the same type of coin as change what did Lauren buy, and what did she receive as change?

Answer 1

A gum and a cracker

Explanation:

She receive 3 of the same type of coin as change => the leftover change should be divisible by 3

If she buy a gum and a cracker, she would be leftover with 100 - (50+35) = 15 cents.

And that is divisible by 3, so we can conclude she bought a gum and a cracker.
