The answer is either 14 or 12
In this question, you are asked how much the maximum revenue. Since candy Y sold for a higher price than candy X, that means you have to sell candy Y as much as possible.
The number of candy Y must be >= 3 times candy X. Since this won't limit candy Y selling, then you can convert all 36 candy into candy Y and 0 candy X
36 candy (Y) >= 0 candy(X) ----> the requirement is met.
<span>The revenue would be 36 candy Y * $3/candy Y= $108</span>
