The correct question in the attached figure
Let
x-------------> <span>the number of granola bars
y-------------> the pounds of fruit
we know that
if 12 bars------------> cost $12
1 bars--------------> X
X=12/12---> x=$1
1 bar---------> cost $1
if 9 pounds of fruit----------> cost $36
1 pound-------------------> X
X=36/9--------> x=$4
1 pound -------> cost $4
</span><span>expression for the total cost=(1)*x+(4)*y----------> x+4y
</span><span>x=12
y=9
then
</span>the total cost=12+4*9----- $48
<span>an inequality that compares
the total cost with the amount you have to spend is
x+4y<=48
</span>
using a graph tool see the attached figure
<span>the inequality that models the number of granola bars you need to buy is
</span>
x<=12 the solution for the number of granola bars is the interval [0,12]

Answer:
<h2>x = 4</h2>Step-by-step explanation:
ΔLMN and ΔPMQ are similar. Therefore thw sides are in proportion:
We have:
LM = 3 + 9 = 12
PM = 9
NM = x + 12
QM = 12
Substitute:
<em>cross multiply</em>
<em>divide both sides by 9</em>
<em>subtract 12 from both sides</em>
