Question $7$: You and your roommates have started a business that offers end$-$of$-$semester apartment cleaning services for a flat rate. The rate you decide on covers unlimited carpet cleaning, wall scrubbing, bathroom deep cleaning, appliance detailing, and window washing. The majority of your customers appreciate the straightforward pricing option. However, you realize that you have lost business in situations where the owners have smaller apartments or need fewer types of cleaning services included. After all, not all apartments are the same $-$ some have fewer appliances, different floor coverings, etc. Which of the options listed below would be the most effective pricing model for your services to address this issue, and why?

Market$-$based pricing, because customers are more likely to pay for services they don't need if those services are competitively priced against similar offerings from your competitors

Dynamic pricing, because it allows you to adjust prices based on the fluctuating cost of the cleaning supplies

A La Carte pricing, because customers will be more likely to pay for only the selected services that meet their needs
