Number of days Val rented the bicycle is 8
Given that val paid a flat rental fee of $55.00 plus $8.50 each day
The total cost was $123
To find: number of days she rented the bicycle
Let "a" be the number of days she rented the bicycle
Rental fee = $55.00
Fee for one day = $ 8.50
So total cost is equal to rental fee and fee for "a" days
Total cost = rental fee + (number of days she rented the bicycle x Fee for one day)
[tex]123 = 55.00 + (a \times 8.50)[/tex]
[tex]123 = 55 + 8.50a[/tex]
123 - 55 = 8.50a
8.50a = 68
[tex]a = \frac{68}{8.50} = 8[/tex]
Thus number of days she rented the bicycle is 8
