There is no variable in the question, but the instinct is to create some variable for the total number of rolls. Any time you start to create a variable out of thin air, ask yourself whether it makes more sense to create a NUMBER rather than a variable. If so, you can (almost always) treat it as a "Hidden Plug In" question, make up the number, and go from there!
Lets say the total number of rolls was 5. Total production cost was $300, so it cost $60 per roll. 4 rolls were sold for 50% more than production cost, so 4 rolls were sold for $90 each, or a total of $360. The one remaining roll was sold for 20% less than $90, which is $72. Revenue was $360+$72 = $432. Cost was $300. Profit was $432-$300 = $132.
Answer choice C.

Assume a total of n rolls were sold -> Thus, the average would be: 300/n. (total cost over total rolls sold).
(4/5 * n) ( 1.5 * 300/n) + (1/5 *n)(80/100 * 1.5 * 300/n) - 300 -> The n's cancel each other out.
360 + 72 - 300 = 132.
(4/5 * n) ( 1.5 * 300/n) + (1/5 *n)(80/100 * 1.5 * 300/n) - 300 -> The n's cancel each other out.
360 + 72 - 300 = 132.
