To find the percent of increase, you can follow these steps:
Step 1: Calculate the difference between the two numbers.
In this case, the difference between 70 and 50 is 20.
Step 2: Divide the difference by the original number (50).
20 divided by 50 is 0.4.
Step 3: Multiply the result by 100 to obtain the percentage.
0.4 multiplied by 100 is 40.
Therefore, the correct answer is C. 40%.
