Answer:
y = 156(0.82)x
Step-by-step explanation:
Since it is decreasing by 18% you need to subtract .18 from b (which equals 1) and it gives you 0.82.
21:18, 42:36, 73:54.
Basically numbers that can be multiplied from the original ratios. Like 7:3, 21:18. 7 is mulitplied 3 times to get 21 and 18 is mulitiplied by 3 7 times to get it. Hope that helps.
