Change 1 hour and 25 minutes to the correct notation:
1 hour and 25 minutes = 60 minutes + 25 minutes = 85 minutes
Do
$\frac{85}{60}=\frac{x}{100}$
So
$x=\frac{85\cdot 100}{60}$
$x=\text{141.67 minutes}\to \text{1.42 hours}$
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
