mario earned three times as much monry last year as his wife elena. the total amount that the two earned was 11,000. how much money did elena earn

I say divide 11,000 by 3 and that will get the amount Mario got, because he earned 3 times his wife. Then take that number and subtract it from 11,000 and you'll get how much money Elena made. to check your answer add the 2 numbers together
