Which equations could model this problem?
a 5 lb bag of potatoes costs $3. what is the unit price p per pound?
choose all answers that are correct.
a. 3/5=p
b. 3p=5
c. 5/3=p
d. 5p=3

To find out how much 1 pound cost you have to divide 3 by 5.
 The right answer would be A. 3/5=P (which is equal with 0.6 ).
You can think this way.
if 5lb costs $3
   1lb cost x$
x=3*1/5=0.6 $
So the right answer is A.

I think the correct answers among the choices presented above are options A and D. The unit price is calculated by dividing the mass of potatoes and the price for that given mass. Therefore, 3 divided by 5 or p = 3/5. The expression is also equal to 5p = 3.
