Jill, Mateo, and Rasheed each have some stickers.
 • Jill has 430 stickers.
 • Mateo has 110 more stickers than Jill.
 • Rasheed has 90 fewer stickers than Mateo.
 Which equation can be used to find r, the number of stickers Rasheed has?
 430 – 110 + 90 =D
 430 + 110 - 90 =r
 430 - 110 - 90 =
 430 + 110 + 90 =r
