Matt was babysitting for friend's parents Saturday morning and was paid an $10 per hour for 3 hours. Later that evening, he was baby sitting 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?

$16.25 per hour

Step-by-step explanation:

Given that:

First babysitting pay :

$10 per hour

Duration = 3 hours

Earning = $10 * 3 = $30

Second babysitting pay:

$20 per hour

Duration = 5 hours

Earning = 20 * 5 = $100

Average rate of pay per hour for the day:

Total amount earned / total hours worked

$(30 + 100) / (3 + 5) hours

$130 / 8 hours

= $16. 25 per hour
