1.
a train car can hold 1500 pounds of cargo that occupies 138 cubic feet of space. a computer
desk weighs 50 pounds and occupies a space of 4 cubic feet. a single drawer file cabinet weighs
30 pounds and occupies a space of 3 cubic feet. which system of equations can be used to find
the total number of computer desks, d, and single drawer file cabinets, c, that can be carried in
the train car?
a. 4d + 3c = 138
50d + 30c = 1500
c. 50d + 30c = 138
30d + 3c = 138
b. 50d + 30c = 1500
50+ 4d = 1500
d. 4d + 3c = 138
30 + 3c = 1500
