The original stock price was $88. On the first day, that increased by $19.40, resulting in a new price of $107.40.
On the second day, that $107.40 decreased by 5 3/4%. To obtain the new stock price, subtract 5 3/4% from 100% and mult. $107.40 by the result (in fractional form):
(100% - 5 3/4%)$107.40 => 0.9425($107.40) = $101.22 (answer)
We assume, that the number 28.52 is 100% - because it's the output value of the task.
<span>2. We assume, that x is the value we are looking for. </span>
<span>3. If 28.52 is 100%, so we can write it down as 28.52=100%. </span>
<span>4. We know, that x is 36.8% of the output value, so we can write it down as x=36.8%. </span>
5. Now we have two simple equations:
1) 28.52=100%
2) x=36.8%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
28.52/x=100%/36.8%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 36.8% of 28.52
28.52/x=100/36.8
<span>(28.52/x)*x=(100/36.8)*x - </span>we multiply both sides of the equation by x
<span>28.52=2.71739130435*x - </span>we divide both sides of the equation by (2.71739130435) to get x
<span>28.52/2.71739130435=x </span>
<span>10.49536=x </span>
<span>x=10.49536</span>

Answer:
(x² - 13x - 10) sq. ft.
Step-by-step explanation:
f(x) = (x - 5) (3x + 2)
= 3x² + 2x - 15x - 10
= (x² - 13x - 10) sq. ft.
