Final answer:
To decide which dog sitting service is more economical for 5 hours, compare their total costs after applying any fees or discounts. Multiply the hourly rate by 5 and add additional fees to get a total for each service, then choose the lower cost.
Step-by-step explanation:
The economic choice between Derrick's Dog Sitting and Darlene's Dog Sitting for 5 hours of service depends on the pricing details of both services, which are not provided in the question. To determine which service is more economic, you would need information such as their per hour rates, any initial service fees, or special package deals they may offer for multiple hours of service. Once you have the pricing, you would multiply the hourly rate by 5, add any additional fees, and compare the total costs.
For example, if Derrick's Dog Sitting charges $10 per hour without additional fees, 5 hours would cost $50. If Darlene's Dog Sitting charges $12 per hour but offers a 10% discount on services over 4 hours, then 5 hours would cost $12 x 5 hours = $60 before discount and $60 - ($60 x 10%) = $54 after discount. In this hypothetical scenario, Derrick's Dog Sitting would be the more economical choice.
