Answer:
No
Step-by-step explanation:
The relationship between the number of pies and the cost is not proportional. This is because the third pie is at half price, meaning it's not consistent with the price of the other two.

So,
123/20 is over 1. The denominator is 20, so what I would do is find out how many <em>whole </em>20's would fit in 123.
The result is that 6 20's would fit in 123 with 3 left over.
The answer is six and three-twentieths (6 3/20). It's already in simplest form.
C = 25 because the amount of broth doesn't change
d = 60 because you add the total before to the new total
5 x 2 x 3 = 30
Therefore your answer is A. 30
