The cost of producing x soccer balls in thousands of dollars is represented by h(x) = 5x + 6. the revenue is represented by
ko 9x2 which expression represents the profit, (k-1)(x) of producing soccer balls?

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
