Val has rented the bicycle for 8 days.

Step-by-step explanation:

Given,

The total cost for rent a bicycle = $123

Fixed rental fee = $55

Charge of 1 day = $8.50

Solution,

Let the total number of days Val rented the bicycle be 'x'.

The total cost for rent a bicycle is the sum of fixed rental fee and charge of 1 day multiplied with  total number of days.

Now framing the above sentence in equation form, we get;

The total cost for rent a bicycle = Fixed rental fee + Charge of 1 day × total number of days

On putting the given values, we get;

So the equation can be written as;

Now we solve the expression for calculating total number of days, we get;

Hence the equation is .

Thus Val has rented the bicycle for 8 days.
