The cost to rent a tube from Tubes-R-Us is $2 plus $0.50 per hour. The cost to rent a tube a tube at Rockin' River is $1 plus $0.75 per hour. After how many hours will the cost of renting a tube at Tubes-R-Us be the same as the cost of renting a tube from Rockin' River?

4 hours

Step-by-step explanation:

0.5 times 4 hours = 2 dollars. 2 dollars + 2 dollars = 4 dollars

0.75 times 4 = 3 dollars. 3 dollars plus 1 dollar = 4

4 hours

Step-by-step explanation:

System of Equations:

(Tubes). c = 2 + .50h

(Rockin).  c = 1 + .75h

set them equal to each other and solve for ’h’

2 + .50h = 1 + .75h

1 = .25h

h = 4

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
