Answer: See explanation
Step-by-step explanation:
Let the cheese pizzas be denoted by x.
Since pepperoni pizzas is 4 less than twice the number of cheese pizzzas. This will be:
= (2 × x) - 4.
= 2x - 4
Since combo pizzas is 8 less than the number of cheese pizzas. This will be:
= x - 8
Then we add all the pizzas and equate to 110. This will be:
x + (x - 8) + (2x - 4) = 110
x + x - 8 + 2x - 4 = 110
4x - 12 = 110
4x = 110 + 12
4x = 122
x = 122/4
x = 30.5
Therefore, cheese pizza = 30.5
Combo pizza = x - 8 = 30.5 - 8 = 22.5
Pepperoni pizza = 2x - 4 = 2(30.5) - 4 = 57
