Isn't it the "setup" that you should be learning?

We have 'x' bicycles per week.

We have C(x), the cost to produce x bicycles.

We have p(x), the price / bicycle, given production of 'x' bicycles.

Requested Items

Weekly Revenue = R(x) = x*p(x)

Weekly Profit = P(x) = R(x) - C(x)

How's that memory trigger doing?
