The formula for the percent increase is:
Substituting the given values into the above equation: 
After rounding, the answer is 22%
The other answers represent possible mistakes that could have been made: 18% is the mistake of dividing by the final value, not the initial value; 10% is the mistake of dividing by the sum of the final and the initial values; and 21% is the mistake of improper rounding or not doing the division to the third digit.

What percent (%) of 50 is 30?
What percent (%) of 50 is 30?
The original number in this problem is 50 and you must find the percentage of 30 from 50.
Another way to view this problem is what percentage of the original 50 equals 30.
Let x equal the percentage:
50(x) = 30
50x = 30
In order to change the decimal 0.6 to a percentage multiply by 100:
0.6 x 100 = 60%

In order to convert numbers to a percent, it is easiest to set up a ratio.
We know that percent is just per-cent or per-100, another way to write this is to divide the number by 100.
We would set up the ratio below with x being the number we are looking for:
To solve this, we can cross multiply, but to make this an easier multiplication we want to reduce any fractions that can be reduced. The 8/40 on the right will reduce to become 1/5.
Now we cross multiply 5 times x and 1 times 100 to get:
Dividing both sides by 5 will give us the percent.
