Atwater Chemicals produces an engine additive for machinery. The additive is produced by adding various ingredients to a petroleum$-$based lubricant. Atwater purchases the lubricant from two suppliers, Woodlawn Petroleum and Spokane Chemicals. The quality of the final product depends directly on the quality of the lubricant. If the lubricant is "off," Atwater has to dispose of the entire batch. Because all lubricant can be "off," Atwater uses a measure it calls the "yield," which is computed as

Yield $=$ Good output $$ Input

where the output and input are both measured in barrels. As a benchmark, Atwater expects to get $12$ barrels of good output for every $16$ barrels of lubricant purchased for a yield of $75$ percent $(=12$ barrels of output $16$ barrels of lubricant$).$
