Real World Word Problem for House Wives

This is the kind of word problem we should have had to work in school:

6. Sam has a desk job and wears jeans to work every day. If Sam has 4 pairs of jeans and also gardens at the end of the day 20% of work days, how often does his wife need to wash his jeans? (Bonus points for answers that don’t require a wash for every wearing.)

I wonder whether HomeEcc classes back in the day covered this. It’s just another reason I wish I was born 100 years ago.

Pensively,
Miss Mary Clare

PS: When you have the answer, would you please raise your hand and share with the class? Thank you!
