In most cases when a percentage is being deducted, it is easier to look at it as how much you get.
If 25% is deducted, the Elena will take home 75% of her salary.
75% as a decimal is .75
Let h=the number of hours Elena works
.75(12h)=900
9h=900
h=100
ANSWER: Elena needs to work 100 hours to take home $900.
Hope this helps you understand the process.
