Allison earned $200 the first month she worked and $250 the second month she worked. By what percent did her salary increase?

25%

Step-by-step explanation:

From the question, we are informed that Allison earned $200 the first month she worked and $250 the second month she worked.

The percentage increase in her salary will be calculated as:

= Salary Increase / Old salary × 100

= (250 - 200) / 200 × 100

= 50/200 × 100

= 1/4 × 100

= 25%

The percentage increase is 25%
