We are given the equation
$$9(e+5)=225$$
9 represents the 9 officers, e represents the entrance fees for the amusement park
and 5 is for the meals. Total cost is 225
we have
$$9(e+5)=225$$
divide both sides by 9
$$e+5=225/9$$
or$$e+5=25$$
Subtract 5 form both sides
$$e=25-5$$
$$e=$20$$
so the entrance fees is $20
