Answer: 25%
Step-by-step explanation: To find the percent increase, we divide the amount of change by the original number.
The amount of change is the difference between the two numbers which in this case is 375 - 300 and the original number is 300.
.
375 - 300 is 75 so we have 75/300 which is 0.25 as a decimal.
Now, remember we want to find the <u><em>percent</em></u><em> </em>increase so we need to write 0.25 as a percent.
We do this by moving the decimal point 2 places
to the right to get 25%.
So when a number changes from 300 to 275, it's increasing by 25%.
