Question

8.) In a carnival game, you gain $2 if you win and lose $1 if you do not win. If

someone plays 30 times and has a net loss of $6, how many wins were there?

Answer 1

Explanation:

Somebody plays 30 times

L+W = 30, where L and W are number of losses and wins, respectively.

L = 30-W

Net after 30 plays is $6

2W - 1L = 6

2W - (30-W) = 6

3W = 36

W = 12

W = 18

17 wins
