Rachel has found that the time it takes for her to make her favorite dessert decreases the more times she makes it. The time it takes in minutes (Al) can be modeled by: M= 72 — 0.75n, where n is the number of times that Rachel has made the dessert. a. How long will it take Rachel to make her dessert the fifth time?
b. After how many times will Rachel be able to make her dessert in 63 minutes?
c. How long will it take Rachel to make her dessert the 40th time? Do you think this is reasonable?
