1/2(6 pint)=3 pints of red
3 pints/0.30=10 pints The 3 pints of red in the 6 pints will make 10 pints of the orange shade, so you need to add 4 pints yellow to the 6 pints to make 10 pints.

Consider that the 6 pint mixture of red and yellow paints is 50% red, and the yellow is like a carrier. Wanted is 30% red, using added yellow to reduce the concentration of the red paint. Adding the yellow adds volume but does not add red paint.

Let y be the volume in pints of yellow paint.

Solve for y.
