Question 89331
blueberry bushes and peach trees would sell well there. Linda can buy blueberry bushes from a supplier for $2.50 each and young peach trees for $5.50 each. She wants to know what combination she should buy and keep her outlay to $500 or less. Write and inequality and draw a graph to depict what combinations of blueberry bushes and peach trees she can buy for the amount of money she has. Explain the graph and her options. 
------------
Let # of blueberry be "b"; Let number of peach be "p"
Value of blueberry trees is 2.5b
Value of peach trees is 5.5p
-------------
INEQUALITY:
2.5b + 5.5p <= 500
------
Solve for b to get:
b <= -(5.5/2.5)p + 500/2.5
----------
Graph:
{{{graph(400,300,-20,100,-20,250,(-5.5/2.5)x+(500/2.5))}}}
-------
The vertical axis is a count of # of blueberry bushes
The horizontal axis is a count of # of peach trees.
Points on the line give # of peach and # of blue (p,b) trees
she can buy for $500. 
Points below the line in the 1st quadrant give p,b combinations where
she would be spending less than $500.
