Step-by-step explanation:
The -1 affects the coefficient of the entire term.

I think you have to choose any numbers in the graph to solve for Rafael and Ava
25 is equal to 20% of 125
As the increase is 75 (200-125), you've then got to divide the increase by each part to find out how many times it increases.
75/25= 3
20*3= 60
Therefore, there is an increase of 60%
Hope this helps :)
