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 mulch 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 (a clearer view can be seen in the attached excel file):

Table A: Price List:
SERVICE PRICE LABOR MATERIAL
Mow lawn $70 1 hr $3
Edge $25 0.25 hr $2
Fertilizer treatment $130 0.25 hr $40
Weed prevention $80 0.25 hr $25

Multiple services 5% discount times the number of services

Workers are paid at a rate of $10 per hour, and overhead is charged at 120% (or 1.2 times) labor costs. For ex, 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. Labor hours shown in Table A are total hours for the three-person crew.
