Answer:
<h2>Model B</h2>
Step-by-step explanation:
The model needs to show 1.8 because 2 x 0.9 = 1.8. Model B is the only model that shows this.
<em>Hope this helps</em>
#2 or B is not a function because it has 3 as X twice
38 because 80% of 20 is 18 and then add the 2
It is 71 because 0 is less than 5, so it stays the same.
