You really shouldn't fib to your math tutor. If, in fact, you had tried to solve the problem every which way, then you would have solved it because every way must include the right way.

Let be the quantity of juice to add to the 3 quarts of soda. Then is the amount of pure juice in the fruit juice blend. The total amount of liquid in the final mixture has to be quarts and the amount of pure juice in that mixture has to be AND it has to be the same as the amount of pure juice in the blend. So:

Just solve for
