Before starting to paint, Bill had 130 ounces of blue paint, 164 ounces of red paint, and 188 ounces of white paint. Bill painted four equally sized stripes on the wall, making a blue strip and red strip a white strip and a pink strip. Pink a mixture of red and white not nessesaraly in equal amounts. When he finished he had an equal number of of red paint, blue paint, and white piant left. How many ounces of paint did he have left.

Answer 1

Let $x$ be the amount of paint in a strip. The total amount of paint is $130+164+188=482$. After painting the wall, the total amount of paint is $482-4x$. Because the total amount in each color is the same after finishing, we have

\[\frac{482-4x}{3} = 130-x\]\[482-4x=390-3x\]\[x=92\]

Our answer is $482-4\cdot 92 = 482 - 368 = \boxed{114}$.
