Answer:

x was increased by 250%

Step-by-step explanation:

You know that x is being increased because x got greater, so it is being increased, and you know that it is a 250% increase because you have 3.5x, and you multiply 3.5*100, and get 350% and think you're done, but you actually have to subtract 100% because x=100%, so the answer is 250%.

Final answer:

To find the percent change of x when we got 3.5x, we can use the formula ((Final Value - Initial Value) / Initial Value) * 100. In this case, x was changed by 250%.

Step-by-step explanation:

To find the percent change of x, we need to compare the initial value of x to the final value of 3.5x. The formula to calculate percent change is:

Percent Change = ((Final Value - Initial Value) / Initial Value) * 100

In this case, the initial value is x and the final value is 3.5x.

Percent Change = ((3.5x - x) / x) * 100

= (2.5x / x) * 100

= 250%

Therefore, x was changed by 250%.
