Answer:
9 hours.
Step-by-step explanation:
Let x represent number of hours.
We have been given that Oceanside Bike Rental Shop charges a 18 dollar fixed fee plus 7 dollars an hour for renting bike.
The cost of renting bike for x hours would be [tex]7x[/tex].
The total cost of renting bike for x hours would be cost of x hours plus fixed charges that [tex]7x+18[/tex].
We are told that Jason paid 81 dollars to rent a bike. To find the number of hours, we will equate total cost of renting bike for x hours by 81 as:
[tex]7x+18=81[/tex]
Let us solve for x.
[tex]7x+18-18=81-18[/tex]
[tex]7x=63[/tex]
[tex]\frac{7x}{7}=\frac{63}{7}[/tex]
[tex]x=9[/tex]
Therefore, Jason paid for 9 hours to have the bike check out.
