The third one because it says 4 of 7 and the rest which is 3 eat a school meal
So the ratio is 4:3
<em>let the charges of washer <u>= x ..
</u></em><em>charges of dryer is three times than <u>x = 3x
</u></em><em><u>as we know their addition is 600 so
</u></em><em><u>x + 3x = 600
</u></em><u><em>4x = 600
</em></u><u><em>dividing 4 on other side we get
</em></u><u><em>x = 600 / 4
</em></u><em><u>x = 150..
</u></em><em><u>charges of washer = x= 150 dollars
</u></em><u><em>charges of dryer = 3x= 3 (150) = 450 dollars</em></u>
