Question

Oceanside Bike Rental Shop charges 12 dollars plus 6 dollars an hour for renting a bike. Write an expression for the cost of renting bikes for x hours.

Answer 1

`y = 12 + 6x`

Explanation:

Given

`Base\ Amount = 12`

`Additional = 6` per hour

Required

Determine the expression for the cost in x hours

Represent the cost with y

y is calculated using the following expression

`y = Base\ Amount + Additional * x`

Where x represent the number of hours.

Substitute values for the base amount of bike and the additional cost per hour

`y = 12 + 6 * x`

`y = 12 + 6x`

So, the expression to determine the cost of bike in x hours is:
`y = 12 + 6x`
