You are spreading fertilizer on a golf course at the rate of 40 pounds per 10,000 square feet. if the course is 320 acres, how many tons of fertilizer will be needed?

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.
