Amanda and Todd purchase candy, popcorn, and pretzels at the stadium. If a package of candy costs half as much as a bag of popcorn, how much more money did Amanda and Todd spend on the candy than on the popcorn and pretzels combined?

ITEM ------- # OF ITEMS PURCHASED ------- PRICE PER ITEM
Candy ----------------------- a ---------------------------- x
Popcorn --------------------- b ---------------------------- 2x (since a package of candy costs half as much as a bag of popcorn)
Pretzels --------------------- c ---------------------------- z

Question: ax-(2bx+cz)=?

(1) The cost of a bag of popcorn is equal to the cost of a pretzel --> 2x=z --> substitute in the question: ax-(2bx+2cx)=x(a-2b-2c)=?. Not sufficient.

(2) Amanda and Todd purchased 24 packages of candy, 6 pretzels, and 6 bags of popcorn --> a=24 and b=c=6. Not sufficient.

(1)+(2) Substitute the values from (2) into (1): x(a-2b-2c)=x(24-12-12)=0, thus Amanda and Todd spent equal amount of money on the candy AND on the popcorn and pretzels combined. Sufficient.

Answer: C.

Hi Bunuel.
I am a bit confused over the usage of words in the questions.
The question explicitly states that "a package of candy costs half as much as a bag of popcorn" then shouldn't a=b/2 rather than #of bags of candies=half of the #of bags of popcorn.

Columns had wrong labels (PRICE PER ITEM and # OF ITEMS PURCHASED should have been reversed). Edited.

The problem I found with the question is whether bag and package are same or not.
In that case I marked E but when I re read the question I just got confused.
though option 1 seems a bit way ward and unclear.
answer would be C in case the the cost of bag of popcorn is equal to the cost of bag of pretzel.
option 1 is not clear as such
