Answer:

the charge is $5 dollars per mile
Step-by-step explanation:
He truck is rented at $40 per day plus they charge per mile of use the truck travel 15 miles in one day and the total charge was 115
LEt x be the charge in dollars per hour
Initial charge is 40 and 15 miles travelled in one day
total charge = 15x + 40
Given : total charge is 115
So the equation becomes

Now we solve for x
Subtract 40 from both sides

Divide both sides by 15
x= 5
so , the charge is $5 dollars per mile
(2+4)/(-2-d) = -2
6 = -2(-2-d)
6 = 4 + 2d
2 = 2d
1 = d
Splashtown: 25 + 1x
Schlitterbahn: 40
25 + 1x = 40
-25 -25
0 1x = 15
x = 15
So after 15 rides, Schlitterbahn would be cheaper than Splashtown.
The Answer Is 4.35. Hope This Helps.
