Annual profit in thousands of dollars is given by the function, P(x) = .1x2 + 50x  300, where x is the number of items sold, x ¡Ý 0.
find the profit for 5 different values of x

algebra 
Reiny,
I am pretty sure you meant
P(x) = .1x^2 + 50x  300
e.g. x = 4
P(4) = .1(4^2) + 50(4)  300
= 1.6 + 200  300
= 101.6
Pick any other 4 values of x , and follow my steps
