Final answer:
Lionel should continue to offer the shrub-trimming service because it generates a profit of $5.
Step-by-step explanation:
Lionel's lawn care company charges $15 for their standard package of mowing, edging, and trimming, and they charge $25 for this service. For a total price of $40, Lionel will also trim shrubs, which adds an additional $10 to the total cost of the standard package.
To determine whether Lionel should continue to offer the shrub-trimming service, we need to compare the cost of offering the service with the additional revenue it generates. In this case, the cost of offering the service is $10, while the revenue generated from offering the service is $15 (the additional cost of $10 + the difference in price between the standard package and the total price with shrub trimming, which is $25 - $40). Therefore, Lionel should continue to offer the shrub-trimming service because it generates a profit of $5.
