Rapid Motors Inc. currently sells 5,100 Type A Premium engines and 4,300 Type 8 Classic engines per year. Type A engines have a sales price of $1,100 per unit and Type B have a sales price of $500 per unit. This year, the company is introducing a better and improved Compact Engine that will substitute the Type B engine entirely, therefore sales of Type B will cease as soon as the Compact Engine is ready to sell. It is expected that Rapid Motors will sell 6,000 Compact Engine units at a price of $600. An independent consultant has determined that if the company introduces the new Compact Engine, the demand for the Type A engine will remain unchanged. What is the amount to use as the annual sales figure when evaluating this project
