Acarnival charges $1.50 per ride after an entrance fee. you paid a total of $30
after 12 rides. (a)write an equation that gives the total cost as a function of the
number of rides. (b) find the total cost for 19 rides.

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!!
