Jeremy should use coupon 2 because when you multiply both the sweaters (36) by .25 you get 9, and then you subtract 36 by 9 which is 27.
But when you use coupon 1 you multiply 18 by .40 which is 7.20 where you subtract 18 by 7.20 which is 10.80. You then add 10.80 with 18 which is 28.80.
I don't even know what the question is but I found the same problem and this was the answer
D. y = 9 because it has a complete zero slope while the y-intercept of the equation is 9, so the equation is y = 9.
Answer:
There you go , happy to help
