The answer is: 1&9 + 11 = 30
Why?
Well, there is actually no real solution to this problem, since this question is asking us to add up 3 numbers so that the sum is 30.
That is impossible. Adding three odd numbers can only result in another odd number. An odd number is just an even number + 1. So adding three odd numbers is simply adding 3 even numbers + 3 1s. 3 even numbers would equal an even number, + 3 would turn it into an odd number.
The question is asking us to add up three numbers from a list, which only includes odd numbers, so that the sum is 30, an even number, therefore there is no possible solution.
A loophole to this question is to 'combine' 2 numbers from the list, in this case, 1 and 9, and add them up with another number, 11. 19 + 11 = 30. Three numbers were used and they were from the list provided.
Using this method, here are all possible solutions:
1&5 + 15
1&7 + 13
1&9 + 11
15 + 1&5
13 + 1&7
11 + 1&9
Answer:
19x + 20
I have a picture of my work here for an explanation
Because it will not be 40 percent of the original, since after 20 percent is gone, the next year itll be 20 percent of the product, instead of the original, so for example, if it was 100, it would go down to 80, and then the next year it would be 20 percent of 80, not 100

In intercept form, the plane that has these intercepts is ...
... x/(x-intercept) + y/(y-intercept) + z/(z-intercept) = 1
... x/1 + y/(-1) + z/2 = 1
... 2x -2y +z = 2 . . . . . in standard form
