Crafter's Supply sells customized handbags. Currently, it sells 18,000 handbags annually at an average price of $90 each. It is considering adding a lower-priced line of handbags that sell for $61 each. The firm estimates it can sell 7,000 of the lower-priced handbags but will sell 3,000 less of the higher-priced handbags by doing so. Fluffy also sells 13,500 scarves each year at an average price of $37 each.

What is the amount of the annual sales that should be used when evaluating the addition of the lower-priced handbags?
