The three person crew worked their way through the neighborhood, mowing lawns, edging, apply fertilizer and weed treatments where necessary and collecting all the clippings for use as much as part of their new green initiative. Their pricing scheme appears in Table A and the mix of orders and service costs appear in Table B.

Workers are paid at a rate of $10 per hour, and overhead is charged at 120% (or 1.2 times) labor costs. For example, for a customer that gets both mowing and edging, their $95 bill would be discounted for two services times 5% for a total of 10% off the $95 straight charge for a cost of $85.50. A customer receiving three services would get a 15% discount off their service bill.

a) Calculate the multifactor productivity for each service combination to determine the one that is most productive from a multifactor perspective.
b) Calculate the overall labor productivity.
