Answer:
2$ parking fee
Explanation:
5$ admission fee for 23 times so you do 5 x 23 (use calculator if needed)
which when you do that it gives you 115
now you just try and figure out if you multiply by 2, 3, or 4. The correct one is 2 so what you do now is 2 x 23 which gives you 46.
make sure it equals 161 so you add 115 and 46 which does give you 161. I hope this helps you :)
