The Weemow Lawn Service wants to start doing snow removal inwinter when there are no lawns to maintain. Jeff and Julie Weems,who own the service, are trying to determine how much equipmentthey need to purchase, based on various job types they have. Theyplan to work themselves and hire some local college students on aper-job basis. Based on historical weather data, they estimate thatthere will be 6 major snowfalls next winter. Virtually allcustomers want their snow removed no more than 2 days after thesnow stops falling. Working 10 hours per Day (into the night), Jeffand Julie can remove the snow from a normal driveway in about 1hour, and it take about 4 hours to remove snow from a businessparking lot and sidewalk. The variable cost (mainly for labor andgas) per job is $12 for a driveway and $47 for a parking lot. Usingtheir lawn service customer base as a guideline, they believe theywill have demand of no more than 40 homeowners and 25 businesses.They plan to charge $35 for home driveway and $120 for a businessparking lot, which is slightly less than the going rate. They wantto know how many jobs of each type will maximize their profit.

Problem 2

A: Alternatively, hiring additional people on a per job basiswill increase Jeff and Julie’s variable cost to $16 for a drivewayand $53 for a parking lot, but it will lower the time it takes toclear a driveway to 40 mins and a parking lot to 3 hours. Will thisaffect their profit?

B: If Jeff and Julie combine the two alternatives (b) and (c),will this affect their profit?

Only problem 2...Specifically, why does the time constraintchange to be less than 100? The correct answers for 2a is 2435 andfor 2b is 2073
