Walks Softly sells customized shoes. Currently, it sells 14,800 pairs of shoes annually at an average price of $59 a pair. It is considering adding a lower-priced line of shoes that will be priced at $39 a pair. Walks Softly estimates it can sell 6,000 pairs of the lower-priced shoes but will sell 3,500 fewer pairs of the higher-priced shoes by doing so. What annual sales revenue should be used when evaluating the addition of the lower-priced shoes?
