A manufacturer of a new patented product has found that she can sell 70 units a week direct to the customer if the price is $78. In error, the price was advertised as $138, and, as a result only 40 units were sold in a week. The manufacturer's fixed costs of production are $50 a week and variable costs of $18 per unit. You are required to: a. Show the equation of the demand function linking price(P) to quantity demand(X), assuming it to be a straight line, is P+2X=218 b. Find where the manufacturer breaks even c. Find the quantity that maximizes profit d. Recommend a unit price which would maximize profit e. Determine the maximum profit f. Find the equation of new demand function, assuming a sudden change in trading conditions resulting a 20% reduction in demand at all price levels
