If Sophia and Isabella work together on a project, they will complete it in 10 days. If Isabella were to work with Kaylee on the same project, they will take a day longer. If Kaylee and Jackson work together, they will take 70% more time than Sophia and Isabella. If Sophia and Jackson were to work together, how many more days will they take to complete the project compared to Isabella and Kaylee working together?
Time taken by Sophia and Isabella in percent = 100%
Time taken by Kaylee and Jackson = 100% + 70% = 170%

Time taken by Sophia and Isabella = 10 days ---- (1)
Time taken by Isabella and Kaylee = 11 days ---- (2)
Time taken by Kaylee and Jackson = 170% x 10 = 17 days ---- (3)

(1) + (2) + (3)
Sophia + Isabella + Isabella + Kaylee + Kaylee + Jackson → 10 + 11 + 17 = 38 days
Sophia + 2 (Isabella + Kaylee) + Jackson → 38 days
Sophia + Jackson + 2 x 11 → 38 days
Sophia + Jackson → 38 - 22 = 16 days

More days to complete the project for Sophia and Jackson compared to Isabella and Kaylee
= 16 - 11
= 5

Answer(s): 5
