There are 10 households living near a lake and a mountain. they can earn income by either chopping wood in the mountain or fishing in the lake. because the lake has a limited number of fish, the more households go to fish, the less each catches. in particular, if x households decide to fish in the lake, then each fishing household makes an amount of $ (10-x). the mountain contains countless woods, therefore the income that a household makes by chopping wood is $2 a day. that each household makes the decision of whether to chop wood or fish in the lake independently.
how many households do you expect to see fishing each day?
