Will give you have following expenses. what should your estimated monthly expense be? (if you can't see the question clearly sorry)

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.

Find the value of x in each case. give reasons to justify your solutions! d q ∈ pr
