Question

HELP PLEASE
Write the inequality that models the number granola bars (12) you need to buy.

Answer 1

the correct question in the attached figure

Let
x-------------> 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

expression for the total cost=(1)*x+(4)*y----------> x+4y
x=12
y=9
then
the total cost=12+4*9----- $48

an inequality that compares
the total cost with the amount you have to spend is
x+4y<=48

using a graph tool see the attached figure

the inequality that models the number of granola bars you need to buy is

x<=12  the solution for the number of granola bars is the interval [0,12]
