#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
