Who can help me solve this problem?

Question

Judith Thompson, the student cafeteria manager, has decided to keep pizza as a permanent menu item after 3 successful months. She has entered discussions with the local pizza supplier to obtain a quantity discount. Currently, each pizza costs $4.75; however, if Judith purchases at least 225 pizzas at a time, their cost is $4.25 each. How much money can Judith save by ordering 225 pizzas at a time?
(a) 258.48 (b) 260 (c) 223.48 (d) Judith will not save any money (e) none of the above
I'm not sure my answer is (e)

Answer 1

50 cents X 225= $112.50. You are right. The answer is (e).

Answer 2

225 pizzas * 4.75 compared with 225 pizzas * 4.25 ?

225 * (4.75-4.25) = 225*0.50 = $112.50.

So Judith saves $112.50 for each batch of 225 pizzas.

I don't know why the supplied alternative answers are what they are - makes me think maybe the question is wrong?

Answer 3

Total cost of pizzas without discount = 4.75*number of pizzas
Total cost of pizzas with discount = 4.25*number of pizzas

Plug in 225 for the number of pizzas, then take the difference between the first expression and the second expression to find the discount.

Answer 4

The difference in price for the pizza will be:
4.75-4.50=.50
if you save .50 on each pizza, you get:
.50*225=112.50

so you have a savings of $112.50, or (e) none of the above.

Answer 5

Savings:
($4.75 - $4.25) * 225 or = $112.50
You got it right, then answer is (e).

Answer 6

she is saving $.50 each pizza so you multiply 0.50 and 225
and that would make 112.50 so the answer is (e)
