Major League Soccer (MLS) rules state the soccer balls are to be inflated to 13 PSI (Pounds per Square Inch). Prior to each game, the referees check the three game balls. If
the game balls are inflated to 1 PSI more or less of the desired weight, they are
approved for use in the game. Which absolute value equation best represents the least
and the most that a MLS soccer ball weighs?
a. lx - 11 = 13
b. lx-131 = 1
c. 1x + 11 = 13
d. (x + 131 = 1
