You are stenciling wooden boxes to sell at a fair. Stenciling takes 2 hours for Box A's design and 3 hours for Box B's design. Profit for Box A is $10 and for
Box B is $20. If you have no more than 30 hours available to stencil but want at
least 12 boxes to sell, how many of each box should you sell to maximize your
profit?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
