Northern Defense manufactures radar systems. It has just completed the manufacture of its first newly designed system, RS-32. Manufacturing data for the RS-32 follow: (Click icon to view more data) Read the requirements. Individual unit time for Cumulative total time: Labor-hours Requirement 1. Calculate the total variable costs of producing 2, 3, and 4 units assuming that Northern Defense uses an 85% incremental unit-time learning model as a basis for predicting direct manufacturing labor-hours. Begin by calculating the cumulative total time in labor-hours using the incremental unit-time learning model. (Round the individual unit time for Xth unit to the nearest whole number.)
