Answer:

The cost of one pound of ground beef is $4.68

Step-by-step explanation:

Let

x ----> the cost of one pound of ground beef

we know that

The cost of 1.5 lbs of ground beef plus $14.53 must be equal to the cost of 3.75 lbs of ground beef plus $4.00 (because Jordan and Victoria spent the same amount)

so

The linear equation that represent this situation is

[tex]1.5x+14.53=3.75x+4.00[/tex]

solve for x

[tex]3.75x-1.5x=14.53-4.00[/tex]

[tex]2.25x=10.53[/tex]

[tex]x=\$4.68[/tex]
