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) d. 112m

b. 14(m − 8)

m is how much drew's box weighed.

You have to subtract it by 8 because marco's boxs are 8 pounds less.

Then, since maro carried 14 boxes you multiply that by 14.
