Answer:
84 hamburgers were sold on Saturday.
Step-by-step explanation:
x = number of hamburgers sold on Saturday.
Divide 336 by 4, because you need 3 times x, plus x.
You are left with 84.
x = 84
<u>Proof</u>
If you multiply 84 by 3, you get 252.
252 cheeseburgers were sold on Saturday.
Add the number of hamburgers sold on Saturday, 84, to the number of cheeseburgers sold.
252 + 84 = 336.
