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.
