PLZ HELP MEEEEEEEE!!!!!!!!!!!!!!!

Answer:
$0.38 cents
Step-by-step explanation:
You would simply divide all the terms by one another.
This gets you $9.12 divided by 4 which is $2.28 per pound.
and then $11.40 divided by 6 which is $1.90 per pound.
Now that you got your 2 values for each pound, you would then subtract them because the word difference means you would subtract the 2 values.
Doing this you would get $2.28 - $1.90 which gets you $0.38 cents
