The model drawing shown is comparing the cost of all the files (1 unit number of files) to the cost of all the markers (3 units number of markers ).
Given that each file cost $2.80 more than each marker, we compare the cost for 1 unit of files with 1 unit of markers.
Hence, with the total difference in the cost for the 1 unit number of files and 1 unit of markers, we can find the number in each unit.
