Question

Val returned a bicycle while she was on vacation. She paid a flat rental fee of $55.00 plus $8.50 each day. The total cost was $123. How many days did she rent the bicycle?

Answer 1

Number of days Val rented the bicycle is 8

Solution:

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)

$123 = 55.00 + (a \times 8.50)$

$123 = 55 + 8.50a$

123 - 55 = 8.50a

8.50a = 68

$a = \frac{68}{8.50} = 8$

Thus number of days she rented the bicycle is 8
