Harman [31]

Answer:

<u>After July, Ana's monthly salary was $1920</u>

Step-by-step explanation:

In May, Ana's monthly salary was $2000. During the next month, the salary increased by 20%, or (0.2)(2000)

2000+(0.2)(2000)=2000+400=2400

So, in June, Ana's monthly salary was $2400. During the next month, the salary decreased by 20%, or (0.2)(2000)

2400-(0.2)(2400)=2400-480=1920

Therefore, after the two changes, Ana's monthly salary was <u>$1920</u>
