The answer is x=13 because the equations equal each other
Answer:

Step-by-step explanation:
Notice when x increases 1, y is 4 times the previous one, so
the function is like 
To determine the constant C, put any pair of (x, y)
Use x = 0, y = 0.2, so
0.2 =
= C * 1 = C
then 
Its 110 cuz it goes up 10% if it was 20% it would be 120
Answer:
0.2
