In a game 5 points are awarded for each game won and 2 points for each game lost. Maria attempted 15 games. If she got 68 points how many games did she lose
2 answers
Maria lost 10 games.
the canned answer is wrong again
games lost --- x
games won = 15-x
5(15-x) - 2x = 68
75 - 5x - 2x = 68
-7x = -7
x = 1
she lost 1 game, and won 14
check:
5(14) - 2(1) = 68
