Cindy Jo's Hair Salon is concerned about its rising costs of supplies, energy, and labor, so it is considering investing in better equipment, which hopefully will reduce the time required to perform most hairstyles as well as result in better perceived quality by its customers. It predicts that the added investment will increase output levels as well as reduce energy costs, since some of the new equipment $($hair dryers$)$ use less electricity.
