For this problem, we can set up an equation. We will represent how many players there are as x. This is what our equation would look like:
13/7 = 540/x
Now we can multiply both sides by x:
13x/7 = 540
Now we multiply both sides by 7:
13x = 91
Now we simplify and divide 13 from both sides to get our final answer:
x = 7
