All you hav to do it plug in what you know

y=20 and x=8

20=8k

divide both sides by 8

20/8=8k/8

and you get 5/2

20/8=5/2

No. The amounts of change are the same, but the original amounts are different. The ratio for the percent increase from 50 to 70 is 20/50, or 40%. The ratio for the percent decrease from 70 to 50 is 20/70, or about 29%.
