$n=$1.28$

Lets see, lets try to put this problem in a formula.
For every 3 pounds of butter you have, you have to pay $3.85
Therefore the equation will be:

$$3.85=3n$

You then have to divide the 3 on both sides in order to isolate the $n$

$($3.85)/3=(3n)/3$

$$1.28=n$

Your final Answer and the price per butter is $1.28
