Select the equation that most accurately depicts the word problem.
a 3-pound tub of butter at n dollars per pound costs $3.85

You first would set it up as a fraction, the cost goes on TOP and the pounds go on the bottom so it would look like this: 3.85/ 3  so you have to make the bottom number equal 1 cause we want to find the cost for 1 pound of butter so we divide 3 by 3 to equal 1 then we divide by 3 on top to find the cost per pound so the equation would look like this:

3.85                        3                1.28                 so it costs 1.28$ per pound
  divided by   =    
3 lbs                        3                  1
