Answer :
50 yards. You are going to be taking away from that 50, so "50 -" should be part of the expression. This eliminates C.
12 skirts that take 3 yards each means 3 yards * 12 skirts which is 3 * 12. This is being subtracted from 50.
We also want to subtract 9 hats * 1 yard which is 9 * 1 = 9
Our expression will look like this: 50 - 12 * 3 - 9 * 1
or 50 - 12 * 3 - 9, which is D

12 skirts take 3 yards each = 12*3
9 hats take 1 yard each = 9*1
Remainder of yards left:
50 - 12*3 - 9*1
50 - 12*3 - 9 Option D
I hope this helps.
