Express revenue as a function of two quantity demand-price pairs and quantity, assuming that demand price is a linear function, where the quantity demand-price pairs are (0,20) and (95,19) and the quantity is 145. (You may find it useful to have intermediate computations that find the coefficients of the demand price function, and the demand price.)
