Sam Squeeze has 10 quarts of a drink that is 60% organge juice. how much pure orange juice must he add to get a drink that is 75% orange juice?
At the start there must be 6Q orange and 4Q water.
Let the total final volume =V
and the volume of orange added =v
so at the end
solve the two equations (1 and 2) to find v
