Question 971365: There are 4 pints of green paint in a gallon bucket.
The paint is made from equal amounts of yellow paint and blue paint.
To create a different shade of green, the mixture needs to be 80% yellow.
How many pints of yellow paint need to be added to the bucket to make the mixture 80% yellow?

+%28+2+%2B+x+%29+%2F+%28+4+%2B+x+%29+=+.8+
+2+%2B+x+=+.8%2A%28+4+%2B+x+%29+
+2+%2B+x+=+3.2+%2B+.8x+
+.2x+=1.2+
+x+=+6+
-------------
6 pints of yellow looks correct. You are
adding to the amount of yellow and also
the total volume of paint
-----------------------
check:
+%28+2+%2B+x+%29+%2F+%28+4+%2B+x+%29+=+.8+
+%28+2+%2B+6+%29+%2F+%28+4+%2B+6+%29+=+.8+
+8%2F10+=+.8+
OK
