To calculate the percent increase from 50 to 75, you start by determining the difference between the two numbers. This difference is found by subtracting the original value (50) from the new value (75).

So, the calculation looks like this:

75 - 50 = 25.

Next, to find the percent increase, you take this difference (25) and divide it by the original value (50):

25 / 50 = 0.5.

To express this decimal as a percentage, you then multiply by 100:

0.5 * 100 = 50%.

This result shows that the percent increase from 50 to 75 is 50%.
