Marco and drew stacked boxes on a shelf. marco lifted 9 boxes and drew lifted 14 boxes. the boxes that drew lifted each weighed 8 lb less than the boxes marco lifted. which expression represents the total number of pounds drew lifted? let m represent the weight of the boxes that marco lifted. a. m − 8 b. 14(m − 8) c. 9(m + 8)

If m = the weight of boxes that marco lifted, and each box that drew lifted was 8 lbs less than marcos boxes, then you would multiply the total number of boxes that drew lifted by the weight of marcos total boxes - 8 or 14(m-8)

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).
