The Nautilus Company, which is under contract to the U.S. Navy, assembles troop deployment boats. As part of its research program, it completes the assembly of the first of a new model (PT109) of deployment boats. The Navy is impressed with the PT109. It requests that Nautilus submit a proposal on the cost of producing another six PT109s. Nautilus reports the following cost information for the first PT109 assembled and uses a 90% cumulative average-time learning model as a basis for forecasting direct manufacturing labor-hours for the next six PT109s. (A 90% learning curve means b = - 0.152004.) (Click the icon to view the cost information.) Read the requirements. Requirement 1. Calculate predicted total costs of producing the six PT109s for the Navy. (Nautilus will keep the first deployment boat assembled, costed at $1,548,100, as a demonstration model for potential customers.) whole number.) X Data table Direct materials cost $ 198,000 per PT109 Direct manufacturing labor time for first boat 15,100 direct manufacturing labor-hours Learning curve for manufacturing labor time per boat 90% cumulative average time Direct manufacturing labor costs EA 41 per direct manufacturing labor-hour Variable manufacturing overhead costs 30 per direct manufacturing labor-hour Other manufacturing overhead 25% of direct manufacturing labor costs Tooling costs $ 278,000 Using the formula for a 90% learning curve, b = In 0.90 - 0.105361 - 0. 152004 In 2 0.693147 2 Tooling can be reused at no extra cost because all of its cost has been assigned to the first deployment boat.The total cumulative time in labor-hours for seven PT109s is 76,552 hours; therefore, the total time to produce six PT109s is 61,852 hours. Now calculate the predicted total costs of producing the six PT109s. (Round your answers to the nearest whole dollar.)

What is the dollar amount of the difference between (a) the predicted total costs for producing the six PT109s in requirement 1, and (b) the predicted total costs for producing the six PT 109s, assuming that for units produced and direct manufacturing labor-hours. Begin by calculating the predicted total costs for producing the six PT 109s, assuming that there is no learning curve for direct manufacturing labor.
