Peter figures he can build the entire tree house by himself in 20 hours. He figures that each additional friend who helps him would improve the time by 10%. He created a table using the algebraic expression n – n(0.10), where n is the previous number of hours.
To the nearest tenth of an hour, how long will it take to build the tree house if 4 friends are helping?
Please answer I need this for a test I will mark you as brainliest :)
