Begin by determining the hours used to produce the six PT109s for the Navy. (Round intermediary calculations and your final answers to the nearest whole number.) The total cumulative time in labor-hours for seven PT109s is hours; therefore, the total time to produce six PT109s is hours. Requirements 1. Calculate predicted total costs of producing the six PT109s for the Navy. (WLJ Boat will keep the first deployment boat assembled, costed at $1,458,800, as a demonstration model for potential customers.) 2. 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 PT109s, assuming that there is no learning curve for direct manufacturing labor? That is, for (b) assume a linear function for units produced and direct manufacturing labor-hours
