17. A high school band needs to make 3 sizes of flags—small, medium, and large—for an upcoming halftime show. The 3 sizes of flags are made by combining 1-foot squares of material that come in 2 colors. Four band members have agreed to make the flags. The information they will need is given to them in the tables below. The table with colors tells how many 1-foot squares of each color are needed for each size flag, and the table with names tells how many flags of each size that each person is to make.
