The cost of packaging the box of chocolates per weight unit is; ¹/₄x²/(x + 2)
We are given the cost of packing the box as;
C(x) = ¹/₄x²
where;
x is the number of chocolates
We are told that a box can never have fewer than 3 chocolates.
Now, the weight of a box of chocolates is given by; W(x) = x + 2
Thus, cost per unit weight is;
C(x)/W(x) = ¹/₄x²/(x + 2)
