The amount of sports drink in a cooler during practice is modeled by the equation
y = 648 - 24x
where y is the number of ounces in the cooler after practice and x is the number of players at practice who take drinks from the cooler.
At the end of practice, there are 240 ounces of sports drink left in the cooler. Every player had some sports drink from the cooler. Based on the equation, how many players were at practice?
