Travis needs to use a combination of the detergents to create 100 ounces of a detergent that is 15% washing soda, 75% water, and 10% borax. Which is true?

The correct answer is that detergent C will be used more than any other detergent. Ax+Bx+Cx = (washing soda, water, or borax). Finally, after doing all the mater you are left with the Matrix of [25 25 50] (vertical) meaning the final row, 50, detergent C will be used more than the others.
