Use the price-demand equation to find the values of p for which demand is elastic and the values for which demand is inelastic. Assume that price and demand are both positive. x = f(p) = 3750 - 6p2 The values of p for which demand is elastic are (Simplify your answer. Type your answer in interval notation.

If the restaurant's daily sales are increasing at the rate of 20 hamburgers per day, how fast is its daily cost for hamburgers increasing? The daily cost for hamburgers increases at a rate of per day.The price-demand equation for hamburgers at a fast food restaurant is given by the equation below. Currently the price of a hamburger is $4.00. If the price is increased by 20%, how will the revenue be affected? x + 500p = 3000 If the price is increased by 20%, the revenue will
