Ok, I was able to get the first word problem by setting up a table. It it possible to set the same table up for this as well....

Thirty ounces of a punch that contains 10% grapefruit juice is added to 50 ounces of a punch that contains 20% grapefruit juice. Find the percent of grapefruit juice in the remaining solution.

Now is says to find the % in the remaining solution, so do i need to figure out what the remaining solution is and the % of juice in it? Can I set up a table to do this. THANKS
