Amy's new summer job at the pool will pay her 9$ per hour. Which term describes this type of hourly income?

Let the total amount earned at a given time be y, if x is the number of hours worked and amount earned per hour is $9, thus the equation representing this information will be:

Total amount earned = (number of hours) * (amount earned per hour)

hence:

y=9*x

y=9x

Answer y=9x
