350 + 4x = 750
x = the amount the fee went up annually.
4x = 750 - 350
4x = 400
x = 400/4
x = 100
The rate of change is 100 dollars per year. The initial value of her business is 350 dollars. To check your work (aka how do you know) if you add 100 dollars to her initial value (350) 4 times you get 750.

Answer:
x = 33
Step-by-step explanation:
Sum of the interior angles of a 5-sided polygon = 540°
Therefore all the interior angles of the given polygon would all be equal to 540°.
Thus:
(4x - 25)° + (3x + 25)° + (2x - 3)° + (4x)° + (3x + 15)° = 540°
Solve for x
4x - 25 + 3x + 25 + 2x - 3 + 4x + 3x + 15 = 540
Combine like terms
4x + 3x + 2x + 4x + 3x - 25 + 25 - 3 + 15 = 540
16x + 12 = 540
16x = 540 - 12
16x = 528
Divide both sides by 16
x = 33
