A distributor ships DVDs to several stores. The shipping boxes contain several DVDs (in their cases) plus a layer of padding at
Snowcat [4.5K]

Answer:

Option B.

Step-by-step explanation:

It is given that,

Thickness of Each DVD case = 14 mm

Thickness of each layer of padding = 10 mm

Length of the interior of the box = 132 mm

Let d represents the number of DVDs that the distributor can fit into one box with two layers of padding.

Thickness of d DVD cases = 14d mm

Thickness of two layers of padding = 10×2=20 mm

Total thickness of d DVD cases and 2 layers of padding = 14d+20

Total thickness must be less than or equal to 132.

14d+20\leq 132

Therefore, the correct option is B.
