Helen Mountain Tubing charges $25 for tube rental and $5 an hour to float down the river. Alpine Tubing charges $30 for tube rental and $2 an hour to float down the river. Create an equation to determine at what point the cost of both tubing companies is the same.

25x - 5 = 30x - 2
25x + 5 = 30x + 2
25 + 5x = 30 + 2x
25 - 5x = 30 + 2x

Answer:

25 + 5x = 30 + 2x

At 5/3s of an hour is when the cost of both tubing companies are the same.

This is when the price of both companies both hit $33.33

Explanation:

25 + 5x = 30 + 2x

move variables by subtracting

25 + 3x = 30

move constants by subtracting

30 - 25 = 5

5 = 3x

x = 5/3
