The first style of dress she wants to make, long with long sleeves, requires 5 yards of fabric, 12 buttons, and 192 yards of thread. The second style, a short-sleeved, short dress, will require 4 yards of fabric, 8 buttons, and 118 yards of thread. Sally has purchased 300 yards of fabric, 600 buttons, and 10,000 yards of thread.

At least half of the dresses should be long and no more than 45% of the dresses should be short in order to offer customers a variety. a.
