Calculate the change in measures of multifactor productivity from the use of a new tool that decreases 7 minutes from a task that previously took 84 minutes with the tool purchase cost of 12,000.00, labor cost of 28.00 per hour, and cost of capital of 32.00%. note that the cost of capital expressed as dollars is the investment multiplied by the percent. in the course engineering economics the capital recovery for an investment will be further developed. assume that the amount produced over a year is based on a full working schedule of 50 weeks working 40 hours each week and the output is the maximum that can be made using the time it takes to produce an item. in your solution find the productivity without the new tool, the productivity with the new tool, and the percent change between without and with the new tool.
