Jane has $7.50 to spend in the candy store. She likes lollipops and gumballs. Each lollipop costs $2.75, and each gumball costs $0.50. If Jane decides to buy 1 lollipop, then what is the greatest number of gumballs Jane can buy? A

Subtract the cost of 1 lollipop:
$7.50 - $2.75 = $4.75

Let the number of gumballs = g. We have:
0.50g = $4.75

Run this through the search engine to get g = 9.5 The problem asks for the greatest number. So we round down to 9 gumballs.
