Answer:
I didn't really understand but I hope this helps sorry if it doesn't!!
Step-by-step explanation:
r = number of rides
1.50r
1.50×12=18
1.50×19=28.50
12 rides = $18
19 rides = $28.50
and if you need the entrance fee:
30-18=12
so it would probably be $12.
and for the total ig fo the last one it would be:
28.50+12=40.50
so $40.50
Again I didn't really understand the question but I hope this helps!!
