Question

I'm painting my house lavender. I'm going to use a mix

of white, blue, and red paint in the ratio 4:3:2. I am
going to need a total of 189 cans of paint. How much do
I need of each color of paint?
If you are feeling stuck, try drawing out the ratio like we
did with paint mixtures.

Answer 1

a lot of paint

Explanation:

Answer 2

Let
`W=4x, B=3x, R=2x`.

The ratio

`4x+3x+2x=189 \\ 9x=189 \\ x=21\implies W=84,B=63,R=42`

Hope this helps.
