Final answer:
To find the percentage change of x when we have 0.03x, use the formula: Percentage change = (New value - Initial value) / Initial value * 100. Simplify the equation to get the percentage change as a negative value, giving the answer as -97%.
Step-by-step explanation:
To find the percentage change of x when we have 0.03x, we can use the formula:
Percentage change = (New value - Initial value) / Initial value * 100
Substituting the values, we get:
Percentage change = (0.03x - x) / x * 100
Simplifying further, we get:
Percentage change = -0.97x / x * 100
Percentage change = -97%
