Justin got pepperoni, banana peppers, and black olives on his pizza for a cost of $7.49. Jake ordered mushrooms and eggplant on his pizza and paid $6.99. Using this information, how much did each topping cost? And what does a plain pizza cost with no extra toppings?
If we assume all of the toppings are the same price
3 toppings = 3t plain pizza = p
3t +p = 7.49
2t+p = 6.99 subtract 2nd equation from first
t = .50 (50 cents)
2t+p = 6.49
2(.5) + p = 6.49
p = 5.49
