A distributor ships DVDs to several stores. The shipping boxes contain several DVDs (in their cases) plus a layer of padding at each end of the box. The DVD cases and layers of padding can be arranged neatly inside each box. Each DVD case is 14mm (millimeters) thick, each layer of padding is 10mm, space, m, m thick, and the length of the interior of the box is 132mm, space, m, m. If d represents the number of DVDs that the distributor can fit into one box with two layers of padding, which of the following inequalities best models the situation?

A. 10d+14 ≤ 132
B. 14d+20 ≤ 132
C. 20d+14 ≤ 132
D. 14d+10 ≤ 132
