Question 498995
1a. Pretty straightforward; if p is the amount you want to spend, then


*[tex \LARGE 6000 \le p \le 10000]


1b. We can set up an inequality, where t is the number of trees:


*[tex \LARGE 30(60) + 84t \le 2500]


*[tex \LARGE 1800 + 84 t \le 2500]


*[tex \LARGE 84t \le 700 \Rightarrow t \le 8.33], hence the maximum number of trees is 8.
