Umm, i don't know how to solve this in any possible ?

The cost consists of a fee and a per ride cost so it will look like:

c=f+pr  where p is the price per ride and r is the number of times ridden...

35=f+5p and 59=f+11p  solve both for f...and set f=f

35-5p=59-11p

35+6p=59

6p=24

p=4  so the price per ride is $4.00, now we can use either original equation to solve for the fee...

35=f+5(4)

35=f+20

f=15 so the cost function is:

c(r)=4r+15  where r is the number of rides taken.

Entry fee=$15.00

One Roller Coaster Ride=$4.00

Ithink the answer is: it is likely.
