Answer:
$8.5
Step-by-step explanation:
Oki, so you have your info laid out. Find out the payment of each material with how much of each material then add it up and subtract from 20. For an easier way, I'll show you.
Two 3-ring binders, each 3-ring binder costs 2.75 so you'll have 2.75 x 2, which equals up to 5.5
Three packages of pencils, each package costs 1.50, therefore it's 1.50 x 3, which is 4.5
Next, two erasers, each one being .75 cents, .75 x 2 is 1.5
Now, add them all. 5.5 + 4.5 + 1.5 = 11.5
Subtract that from $20, 20 - 11.5 = 8.5
Ashton will get $8.5 back.
