Answer:
C=13
Explanation:
To start off you need to work out how much 5 jumbo pizzas cost. One jumbo pizza is 13.00. 13.00x5=65 to get you the price of 5 jumbo pizzas.
Then you need to do 65 divided by 5 which gets you the amount of mini pizzas you need to make up the amount of the jumbo pizzas which is 13.
Hope this helps
