If Levi and Scarlett work together on a project, they will complete it in 10 days. If Scarlett were to work with Jackson on the same project, they will take a day longer. If Jackson and Isabella work together, they will take 50% more time than Levi and Scarlett. If Levi and Isabella were to work together, how many more days will they take to complete the project compared to Scarlett and Jackson working together?
Time taken by Levi and Scarlett in percent = 100%
Time taken by Jackson and Isabella = 100% + 50% = 150%

Time taken by Levi and Scarlett = 10 days ---- (1)
Time taken by Scarlett and Jackson = 11 days ---- (2)
Time taken by Jackson and Isabella = 150% x 10 = 15 days ---- (3)

(1) + (2) + (3)
Levi + Scarlett + Scarlett + Jackson + Jackson + Isabella → 10 + 11 + 15 = 36 days
Levi + 2 (Scarlett + Jackson) + Isabella → 36 days
Levi + Isabella + 2 x 11 → 36 days
Levi + Isabella → 36 - 22 = 14 days

More days to complete the project for Levi and Isabella compared to Scarlett and Jackson
= 14 - 11
= 3

Answer(s): 3
