Is there a grid that came with the problem?
D≈6.37

Just multiply 30 times 2,000 and also multiply 30 times 700. The reason you will multiply it by 30 is because in 1 month there is 30 days. 30 x 2,000= 60000 30 x 700 = 21000 I’m only 9 btw so sorry if I didn’t give a lot of detail lol
<u><em>Answer:</em></u>
<u><em /></u>![-9(\frac{2}{3}x) + 9(1)\\ \\-6x + 9](https://tex.z-dn.net/?f=-9%28%5Cfrac%7B2%7D%7B3%7Dx%29%20%2B%209%281%29%5C%5C%20%20%5C%5C-6x%20%2B%209)
<u><em>Explanation:</em></u>
<u>Before we begin, remember the following rules:</u>
<u>1- Distribution property:</u>
<u />![a(b+c) = ab+ac](https://tex.z-dn.net/?f=a%28b%2Bc%29%20%3D%20ab%2Bac)
<u>2- Simplification of fractions:</u>
<u />![\frac{xy}{yz}=\frac{x}{z}](https://tex.z-dn.net/?f=%5Cfrac%7Bxy%7D%7Byz%7D%3D%5Cfrac%7Bx%7D%7Bz%7D)
<u>3- Signs in multiplication:</u>
+ve * +ve = +ve
-ve * -ve = +ve
+ve * -ve = -ve
<u>Now, for the given problem, we have:</u>
<u></u>![9 (\frac{2}{3}x + 1)](https://tex.z-dn.net/?f=9%20%28%5Cfrac%7B2%7D%7B3%7Dx%20%2B%201%29)
<u>Starting with the distributive property:</u>
<u />
..................>This corresponds to option 1
<u>Now, we simplify the output from the above step:</u>
<u />![-9(\frac{2}{3}x) + 9 = \frac{-9*2}{3}x + 9 = -6x+9](https://tex.z-dn.net/?f=-9%28%5Cfrac%7B2%7D%7B3%7Dx%29%20%2B%209%20%3D%20%5Cfrac%7B-9%2A2%7D%7B3%7Dx%20%2B%209%20%3D%20-6x%2B9)
................> This corresponds to option 5
Hope this helps :)
