Oceanside bike rental charges 11 dollars plus 8 hours for renting. tom paid 51 dollars to rent a bike . how many hrs did he pay to have the bike checked out

Tom paid $51 renting the bike for 5 hours

Step-by-step explanation:

Given:

Oceanside bike rental charges $11 plus $8 per hour for renting.

Tom paid $51 to rent a bike.

To find the number of hours Tom rented the bike for.

Solution:

Let Tom rent the bike for = hours.

Hourly rate of renting = $8 per hour

Using unitary method find cost of renting for hours.

If renting for 1 hour costs = $8

Then for hours, the cost in dollars will be =

Fixed charges = $11

∴ Total cost of renting a bike in dollars for hours will be given as:

Tom paid a total charge of = $51.

So, we have:

Subtracting both sides by 11.

Dividing both sides by 8.

∴

Thus, Tom rents the bike for 5 hours.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
