You can put this solution on YOUR website! For your question, I'll assume that you are a United States resident and thus have a minimum wage of $7.25 per hour.
The equation to determine how many hours you must put in in order to earn $8000 dollars is 7.25*h=8000. 'h' represents how many hours you work.
To isolate the variable, h, you simply need to divide each side of the equation by 7.25. The result is:
h=1103.448276...
Since h is not a whole number, we should round it up (Obviously, you won't be doing exactly 1103.448276... hours of work.). Therefore, you will have to work 1104 hours to get 8,000 dollars.
