Answer:
10
Step-by-step explanation:
f(x)=9-2x
--------------------
f(x)=25
9-2x=25
-9 -9
-2x=16
/-2 /-2
x = -8
---------------------
f(x)=-41
9-2x=-41
-9 -9
-2x=-50
/-2 /-2
x = 25
----------------------
f(x)=17
9-2x=17
-9 -9
-2x=8
/-2 /-2
x = -4
-----------------------
f(x)=-8
9-2x=-8
-9 -9
-2x=-17
/-2 /-2
x = -17/2
The answer is 2 and a half. Because 18 + 6 + 6 + 3 is 33. This is because $18 to get in then $6 for one hour another $6 for an hour and $3 for an half hour.
