Assume you had invested USD 1,000 in a lawn mower to set up a lawn mowing business for the summer. During the first week, you could choose either to mow the grounds at a 143 housing development for USD 1,400 or to help paint a garage for USD 1,360. Each job would take one week. You cannot do both. You would incur additional costs of USD 160 for lawn mowing and USD 80 for garage painting. These costs include USD 60 under each alternative for transportation to the job. Prepare a schedule showing the net benefit or advantage of selecting one alternative over the other alternative.
