A local movie theater charges $7 for each adult ticket and $4.50 for each child ticket.
The theater also charges $3.00 for a large drink and $2.00 for each box of candy.
If the Ufer family has 2 adults and 3 children and will purchase 2 large drinks, write an inequality to find out how many boxes of candy they can buy if they don't want to spend more than $40.
