Salaam I have a simple word problem which I would like to solve in public. I am sure you can agree with me. If one trades labor for 30 days out of 53 days what would be the average days a week one trades? Here is my answer. wk 1 = 7 days of trade wk 2 = 4 days of trade wk 3 = 4 days of trade wk 4 = 3 days of trade wk 5 = 5 days of trade wk 6 = 2 days of trade wk 7 = 1 day of trade wk 8 = 4 days of trade (counts as 1/2 week) Step one. FInd the Sum: Sum = 7 + 4 + 4 + 3 + 5 + 2 + 1 + 4 = 30 Step two. Divide 30 by 7.5 (the total number of weeks) 30 divided by 7.5 is 4, so the average is 4.

Salaam Do you think one can also find the average days per week by dividing 53 days by 30 days of trade? Would that work or would I be finding weeks per day as opposed to days per week?

weeks have nothing to do with the probability a day is used for work. weeks simply enter into it as a multiplication factor of 7 since there are 7 days in a week.
