The baker made the following types of pie. 10 lemon, 20 cherry, 4 blueberry and 16 apple. What percent of the pies are cherry?

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.
