$9,900
10% off of 10,000 is 9,000
10% more than 9,000 is 9,900
The answer is 7 multiple by 10 =70
<h2>22</h2>
In this problem, we need to use <u>multiplication</u> and <u>subtraction</u> method to solve it.

Note that {a = 7} and {b = 6}
First, we need to multiply 4 with {a = 7}, we get:
4(7) = <em>28</em>
<em />
Then, we need to subtract {b = 6} from <em>28</em>, we get:
<em>28</em> – 6 = 22
Finally, this simplifies as:
4(7) – 6 = 22

L = 2W
P = 2L + 2W
Plug 2W in for L.
54 = 2(2W) + 2W
54 = 4W + 2W
54 = 6W
Divide both sides by 6
W = 9
L = 2* 9
L = 18
A = L * W
A = 9 * 18
A = 162 units^2
