Step-by-step explanation:

Regular work week is 40 hours; at $16.50 per hour, that comes to $660.

Subtracting $660 from the toal $948.75 yields $288.75, which represents her pay at the overtime rate of (1.5)($16.50/hr), or $24.75/hour

Dividing $288.75 by this overtime rate of $24.75/hr yields 11.666 ...
