Question

The cost of packing a box of chocolates is given by 1 4 x2, where x is the number of chocolates (a box can never have fewer than 3 chocolates). If the weight of a box of chocolates is given by x + 2, what is the cost of packaging per weight unit? A. 1 4 ⁢ x − 1 2 + 1 x + 2 B. 1 4 ⁢ x 2 − 1 2 ⁢ x + 1 C. 1 4 ⁢ x 2 − 1 2 + 1 D.

Answer 1

The cost of the packaging will be D. 1/4x²/x + 2.

How to calculate the cost?

From the information given, the cost of packing a box of chocolates is given by 1/4x², where x is the number of chocolates and a box can never have fewer than 3 chocolates.

The weight of the box is also given as x+2. The cost of the packaging will be:

= Cost of packing a box of chocolate / Weight of a box of chocolate

= 1/4x²/x + 2.

In conclusion, the correct option is D.
