Matt was babysitting for friend's parents Saturday morning and was paid $10 per hour for 3 hours. Later that evening, he was babysitting for another couple that paid
him $20 per hour for 5 hours. What was Matt's average rate of pay per hour for the
day?

Matt was paid an average of $10 per hour of babysitting for the day.

Step-by-step explanation:

He babysat in the morning for 3 hours being paid $10 per hour. He later babysat in the evening for 5 hours being paid $20 per hour. Since he was being paid two different amounts throughout the day, the average would be $10. He was being paid atleast $10 per hour for babysitting because even though he was being paid $20 in the evening, the lowest amount of money that he was paid, was $10 making that the average.
