ok then since the total is \(282\) the number of entrance only passes is \(282-x\)

the unlimited passes cost $50 so \(x\) of those will be \(50x\) and the entrance only cost $10 so \(282-x\) of those cost \(10(282-x)\) for a total of \[50x+10(282-x)\]

50x + 20(282 - x)

right

set that equal to the total of \(10,680\) and solve \[50x+20(282*-x)=10,680\] for \(x\)
