amtran_bus · Answer

and you are adding 10 oz

28/50

But in those 10 oz is a small percent of seltzer too?

magentama202 · Answer

In the 10 oz, it is only the juice being added. All of the seltzer is in the container and going to stay there.

But the juice contains some seltzer!

magentama202 · Answer

No, so they have a mix of juice and seltzer, and then there is 10 ox of just added. just juice.

magentama202 · Answer

30% of 40 = 12, so there is 12 oz of juice. 10 more oz is added, so now you have 22 oz of juice. The whole mixture is now 40+12, or 52. You now need to find what 30 of 52 oz is in percent.

can you try this???

magentama202 · Answer

100*30/52=57.6923076923% I think this is what you're looking for... you may want to round it to 57.7% or something.
