Problem is to calculate at what price does the company get the most profit, so my solution is to make a function of profit(P) as function of price(x) and it comes out as P(x)=x(-15.4x+3633), then derive it, set the derivative to 0 and look for max. I get an answer of 118 currency. Does it look right? Thanks

S= units sold

x= Price
