Answer
The price per pound of candy is $d\div3$ .
Work Step by Step
The price for $3$ pounds of candy is $d$. Assuming that each pound of candy is priced the same, the price for one pound of candy would be a third of the price for three pounds. To find out what a third of the price is, we must divide by $3$. This gives us a price of $d\div3$ per pound of candy.
