Question

. Val rented 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. Write an equation you can use to find 23 the number of days she rented the bicycle.

Answer 1

123 = 55 +8.50d

Explanation:

The cost after d days will be ...

c = 55 +8.50d

The number of days that make the cost be 123 is ...

123 = 55 +8.50d

Subtracting 55 and dividing by 8.50 gives the solution.

68 = 8.50d

68/8.50 = d = 8

Val rented the bicycle 8 days to bring her total bill to $123.

Additional comment

Your problem statement here would have us use "23" as the number of days she rented the bicycle. We have used "d" in our equation for that purpose. We suspect your actual problem statement may be different. You will need to use the variable it requires.
