Suppose that we have a sample space s={e1, e2, e3, e4, e5} where p(e1)=0. 18, p(e2)=0. 16, p(e3)=0. 22, p(e4)=0. 24, and p(e5)=0. 2. Let a={e1, e3, e5}, b={e2, e3, e4}, and c={e1, e4, e5}.

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.
