Answer:

She would have to work 19.6333 hours but you could probably round it up to 20 hours

Step-by-step explanation:

Multiply 7.50 (the cost of each favor) by 40 (the number of guests) to get the cost of all the favors. Then add up all the costs to get the total cost. Subtract 792 (the savings) from the total cost. Then divide that number by 60 to figure out the number of hours she'd need to work.
