Hello, I was wondering how do I differentiate the 2 days of work done by carpenter from the rest of the 3 5/7 days? I know that the carpenter could do 1/h+4 amount of work a day and the helper at the rate of 1/h. However, when I plucked it into the equation, which ultimately ends up as second degree equation, the answers are wrong.

I would appreciate any help thanks!!
