Answer:
She work 23 hours.
Step-by-step explanation:
Given:
Tracy works at the Pizza Place. She earns $4.50 an hour plus tips.
Last week, she earned a total of $156.00, of which $52.50 was tips.
Now, to find the number of hours she work.
Total salary = $156.00
Amount of tips = $52.50.
So, first we deduct the amount of tips from the total salary:
[tex]\$156.00-\$52.50\\=\$103.50.[/tex]
Thus, the remaining salary = $103.50.
As, given salary she earns an hour = $4.50.
And then, to get the number of hours she work last week by dividing $103.50 the remaining salary by $4.50:
[tex]103.50\div 4.50[/tex]
[tex]=23\ hours.[/tex]
Therefore, she work 23 hours.
