If Kaylee and Ava work together on a project, they will complete it in 10 days. If Ava were to work with William on the same project, they will take a day longer. If William and Lucy work together, they will take 160% more time than Kaylee and Ava. If Kaylee and Lucy were to work together, how many more days will they take to complete the project compared to Ava and William working together?
Time taken by Kaylee and Ava in percent = 100%
Time taken by William and Lucy = 100% + 160% = 260%

Time taken by Kaylee and Ava = 10 days ---- (1)
Time taken by Ava and William = 11 days ---- (2)
Time taken by William and Lucy = 260% x 10 = 26 days ---- (3)

(1) + (2) + (3)
Kaylee + Ava + Ava + William + William + Lucy → 10 + 11 + 26 = 47 days
Kaylee + 2 (Ava + William) + Lucy → 47 days
Kaylee + Lucy + 2 x 11 → 47 days
Kaylee + Lucy → 47 - 22 = 25 days

More days to complete the project for Kaylee and Lucy compared to Ava and William
= 25 - 11
= 14

Answer(s): 14
