C.after the appointed time
Sara paid for 4 hours to have the bike checked out
<em><u>Solution:</u></em>
Oceanside bike rental shop charges 17 dollars plus 9 dollars an hour for renting a bike
Let "x" be the number of hours rented
Then, total cost is 17 dollars plus 9 dollars for "x" hours
<em><u>Thus, we frame a equation as:</u></em>
Total cost = 17 + 9(number of years)
Total cost = 17 + 9x
<em><u>Sara paid 53 dollars to rent a bike</u></em>
Therefore, total cost = 53

Thus sara paid for 4 hours to have the bike checked out
Answer:
Answer is TONE.
Refer below.
Explanation:
When a tone is sounded, a baby's right cheek is touched, and the baby reflexively turns its head to the direction of the touch. After several pairings, the baby turns its head to the right as soon as it hears the tone. In this example, the conditioned stimulus is the TONE.
