The Pacific Boat Company, which is under contract to the U.S. Navy, assembles troop deployment boats. As part of its research program, it completes the assem of the first of a new model (PT109) of deployment boats. The Navy is impressed with the PT109. It requests that Pacific Boat submit a proposal on the cost of producing another six PT 109s Pacific Boat reports the following cost information for the first PT 109 assembled. Pacific Boat uses a 90% incremental unit-time learning model as a basis for predicting direct manufacturing labor-hours in its assembling operations. A 90% learning curve means b =-0.152004.

Prepare a prediction of the total costs for producing the six PT109s for the Navy Begin by calculating the cumulative total time in labor-hours. (Round the individual unit time for Xth unit to the nearest whole number.)
