Tatiana Booth · Answer 1

Let the number of pepperoni pizzas be x

pepperoni = x

veggie = x - 8 [ There were eight fewer veggie than pepperoni]

combo = 3x [T here were three times as many combo as pepperoni]

Given that the total Pizza: 112

x + x - 8 + 3x = 112

5x - 8 = 112

5x = 112 + 8

5x = 120

x = 24

x = 24

x - 8 = 16

3x = 72

So there were 24 pepperoni pizza, 16 veggie pizza and 72 combo pizza
