Then, add to both sides to make the right a perfect square trinomial, which is easy to factor:
Simplify and Factor:
Finally, square root both sides using the even roots property:
x - 5 = ± 2
x = 5 ± 2
x = 3 or x = 7
This will take me a long time, but...
<em><u>Total Cost : 1800</u></em>
<u><em>12 dollars * 16 hours = 192 dollars earned</em></u>
<u><em>0.2 percent * 192 = 38.4 dollars saved</em></u>
A.<u><em>She earns 192 dollars every week</em></u>
B. she will save <em><u>38.4 dollars * 7 weeks = 268.8 </u></em> dollars in a week.
C. 7 days times 4.3 weeks = 30.1 days. <em><u>30.1 days * 38.4 = 1,155.84 dollars every month.</u></em>
D. it will take her about <em><u>2 months</u></em> to save the money. <em><u>To be exact: 1.6 months.</u></em>
Hope this helped!
The answer is 19
