$57.75

Explanation:

Change 1 hour and 25 minutes to the correct notation:

"1 hour and 25 minutes = 60 minutes + 25 minutes = 85 minutes"

Do

85/60 = x/100

So

x = (85*100) / 60

x = "141.67 minutes" -> "1.42 hours"

Add the total number of hours together:

"1.75 hours + 2.33 hours + 1.42 hours = 5.5 hours"

Doug earns $10.50 per hour, so for 5.5 hours, multiply 10.50 by 5.5:

$10.50 * 5.5 = $57.75
