What's the problem? I don't see the equation.
If 9 pizzas cost $67.50 that means that 1 pizza costs 67.50/9 = $7.5
Answer A is incorrect because of false prize of pizza.
B isn't correct because 1 pizza cost $7,5 and not 7,5 pizzas cost $1
C isn't answer because of both reasons from answer A and answer B
D is the answer because it says that you need to pay $7.5 per pizza.
Answer:
2.5(x-1)+4.5(-x-2)
2.5x-2.5-4.5x-9
-2x-11.5
