If Anthony and Michael work together on a project, they will complete it in 9 days. If Michael were to work with Wyatt on the same project, they will take a day longer. If Wyatt and Raeann work together, they will take 100% more time than Anthony and Michael. If Anthony and Raeann were to work together, how many more days will they take to complete the project compared to Michael and Wyatt working together?
Time taken by Anthony and Michael in percent = 100%
Time taken by Wyatt and Raeann = 100% + 100% = 200%

Time taken by Anthony and Michael = 9 days ---- (1)
Time taken by Michael and Wyatt = 10 days ---- (2)
Time taken by Wyatt and Raeann = 200% x 9 = 18 days ---- (3)

(1) + (2) + (3)
Anthony + Michael + Michael + Wyatt + Wyatt + Raeann → 9 + 10 + 18 = 37 days
Anthony + 2 (Michael + Wyatt) + Raeann → 37 days
Anthony + Raeann + 2 x 10 → 37 days
Anthony + Raeann → 37 - 20 = 17 days

More days to complete the project for Anthony and Raeann compared to Michael and Wyatt
= 17 - 10
= 7

Answer(s): 7
