Jade and Chet get a weekly allowance plus x dollars for each time the pair walks the dog. They plan to save 40% of
their combined earnings in one week to purchase a new
app for their smart tablet. Their earnings in a certain week
are represented in the table. If their parents pay $2.50
each time they walk the dog, how much money will they
have to purchase the app?
