Exercise B Assume you had invested $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 housing development for $1,400 or to help paint a garage for $1,360. Each job would take one week. You cannot do both. You would incur additional costs of $160 for lawn mowing and $80 for garage painting. These costs include $60 under each alternative for transportation to the job. Show the net benefit or advantage of selecting one alternative over the other.

Formula Used for This Schedule: Net Benefit = Total Revenue - Total Cost
