Mrs. J wants to find the best deal on a new Harley. The matrix shows the prices of three different models (rows) with four different dealers in her area (columns). The sales tax in her region is 7%. Which matrix A - D shows the final price of each bike including sales tax.

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.
