The cost of packaging the box of chocolates per weight unit is; ¹/₄x²/(x + 2)
<h3>
</h3><h3>How to Solve Algebra problems?</h3>
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)

1/3 = 2/6 = 4/12
Multiply both sides by 2 to get 2/6 and both sides by 4 to get 4/12
