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 the number of days she rented the bicycle, then solve.

Answer 1

The equation that expresses the total cost of Val's bicycle rental can be written as = $55.00 + $8.50. To find the number of days she rented the bicycle, substitute the total cost of $123 into the equation and solve for .

Step-by-step explanation:

The equation that expresses the total cost of Val's bicycle rental can be written as:

= $55.00 + $8.50

Where:

• represents the total cost in dollars
• represents the number of days the bicycle is rented
• $55.00 is the flat rental fee
• $8.50 is the additional cost per day

To solve for the number of days, we can substitute the total cost of $123 into the equation:

$123 = $55.00 + $8.50

Subtracting $55.00 from both sides gives:

$123 - $55.00 = $8.50

Combining like terms:

$68 = $8.50

Dividing both sides by $8.50, we find that = 8.

Therefore, Val rented the bicycle for 8 days.
