sweet [91]

Answer:

She work <u>23 hours</u>.

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:

\$156.00-\$52.50\\=\$103.50.

<em>Thus, the remaining salary = $103.50.</em>

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:

103.50\div 4.50

=23\ hours.

Therefore, she work 23 hours.
