Question 758567: Suppose that the revenue (R), in dollars, from selling (x) clocks is
R(x)= 30x
The cost (C), in dollars, of selling (x) clocks is
C(x)= 0.1(squared 2) + 7x +400
find the Profit Function (P),

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

... Please help me

R%28x%29=+30x
C%28x%29=+0.1x%5E2%2B7x%2B400......you forgot x here 0.1%28squared+2%29
P%28x%29=+R%28x%29-+C%28x%29...substitute R%28x%29 and C%28x%29
P%28x%29=+30x-+%280.1x%5E2%2B7x%2B400%29
P%28x%29=+30x-+0.1x%5E2-7x-400
P%28x%29=+-0.1x%5E2%2B23x-400
