<h2>Greetings!</h2><h3>When multiplying two roots together, you can rearrange the equation so that the roots are next to each other and so are the whole numbers:</h3>
2 x 3 x
x 
<h3>This means that 2 x 3 is simple, = 6,</h3><h3>But when multiplying

you simply multply the two numbers and put them in a square root:</h3>
=
<h3>But this can be square rooted to 6, which then means that the equation is now:</h3>
2 x 3 x 6 = 36
<h3>So the simplified form is 36.</h3>

Okay. So for this equation, she would make $60, plus $5.25 in tips each hour. So for this, she would get $60 + 5.25h. Plug in 4 hours, and she would make $21 off of tips, plus the $60, which brings her up to $81 total. The answer is C.
