Question

25 to 50 points Round to the nearest tenth of a percent if you need to

Answer 1

If you want to calculate percentage increase, then here is your solution:
Percentage increase = Final value-initial value / initial value * 100
= 50-25 / 25 * 100
= 25/25 * 100
= 100%

In short, Your Answer would be 100%

Hope this helps!
