Question 174135
1.a)let x be the amount of money you can spend landscaping
:
{{{6000<=x<=10000}}}
:
b) ok we need 30 tons of rock which costs 60 bucks a ton. 30(60)=1800. If we have a budget of 2500 and we have already spent 1800 then we have to subtract out what is spent to arrive at what is left to work with
:
2500-1800=700. This is what we have left to work with for the trees. lets call the number of trees we can buy t.  Lets write an equation representing what the possibilities are for our trees.
:
each tree cost 84 dollars so {{{84(t)<=700}}}lets solve for x.  
:
{{{highlight(t<=8.33)}}} since we cant buy part of a tree it looks as if the maximum number of trees we can buy at 84 dollars per tree is 8.
:
c.)let see if t=5 makes our inequality a true statement plug in 5 for t and we get {{{5<=8}}}. That indeed hold true for this inequality therefore it is a solution.
