Answer:
(5 , 0)
Step-by-step explanation:
7 * (−9y+4x−20)=0
9 * (−7y+16x−80)=0
-63y + 28x -140 = 0 ......a
-63y + 144x -720 = 0 .....b
b-a: 116x - 580 = 0
116x = 580
x = 5
y = (4x-20)/-9 = 0/-9 = 0
40% Because if the shoe is $80 and went on sail to $50 they would have to raise the original price by 20% there for when they say it’s on sail for 30% off it’s really should just be 20% off
