Answer:

Step-by-step explanation:
Isolate the variable by dividing each side by factors that dont't contain the variable.



-8 -8

Divide both sides by 5.

4/10 x 0.04 = (of means multiply)
0.4 x 0.04 =
0.016
Y = 40
Since,
1st year = 200
2nd year= 200 + 40 =240
3rd year = 240 + 40 = 280
4th year = 280 + 40 = 320
5th year = 320 + 40 =360
6th year = 360 + 40 = 400.
So, basically all you have to do is add 40!
Therefore, the answer is y = 40 Hope this helped! :)
