Currently, GH Co. sells 42,600 handbags annually at an average price of $149 each. It is considering adding a lower-priced line of handbags that sell for $79 each. The firm estimates it can sell 21,000 of the lower-priced handbags but expects to sell 6,200 less of the higher-priced handbags by doing so. What is the amount of the annual sales that should be used when evaluating the addition of the lower-priced handbags?
