We let m be the weight of the boxes Marco lifted. From the problem statement, each box that Drew lifted is eight pounds less than Marco's boxes. It can be represented by (m-8). To find for the total number of pounds Drew lifted, we multiply the expression above by the number of boxes he lifted which is 14. Therefore, the correct answer is option B, 14(m-8).

if m = weight of boxes and the boxes drew lifted were 8 pound less you would have (m-8)

 Marco lifted 14 boxes so the equation would be 14(m-8)
