The second store will pay her a weekly salary of $475 plus an 8% commission. If x represents Rachel’s weekly sales (in dollars) and y represents her total earnings (in dollars), which system of equations describes the problem situation? A. { y = 0 . 12 x y = 0 . 8 x B. { y = 250 + 12 x y = 475 + 8 x C. { y = 250 x + 12 y = 475 x + 8 D. { y = 250 + 0 . 12 x y = 475 + 0 . 08 x
