Looks good amigo for your eqn.
Let's see,
84x%2B60%2A30%3C2500
84x%3C2500-1800
84x%3C700 -----> cross%2884%29x%2Fcross%2884%29%3Ccross%282500%298.33%2Fcross%2884%29
x%3C8.33, Let's say highlight%288%29 trees
We'll see,
84%2A8%2B60%2A30%3C2500
672%2B1800%3C2500
2472%3C2500, GOOD!
If 9 trees,
84%2A9%2B60%2A30%3C2500
756%2B1800%3C2500
2556%3E2500, NOT GOOD
ANSWER ---> 8 trees
Thank you,
