Answer:
Number of pizzas = 6
Step-by-step explanation:
Total amount = delivery fee + cost of the ordered pizza.
delivery fee + cost of the ordered pizza = Total amount
cost of the ordered pizza = total amount - delivery fee
= 56 - 5
= $ 51
Number of pizzas = Cost of ordered pizzas ÷ cost of one pizza
= 51 ÷ 8.50
= 6
