The monthly market demand curve for calculators among economics students is given by P=100-2Q, where P is the price per calculator in dollars and Q is the number of calculators purchased per month. If the Price is $30, how much revenue will calculator makers get each month? Find the price elasticity of demand for calculators. Find the price/quantity combination that would maximize revenues. Draw the demand curve and indicate which portion of the curve is elastic, and which is inelastic.
