A nontoxic wood furniture polish can be made by mixing mineral(or olive)oil with vinegar. To make a 16-oz batch for a squirt bottle, Michael uses an amount of mineral oil that is 4oz more than twice the amount of vinegar. How much of each ingredient is required?
v + (4+2v) = 16
v = 4
so, 4 oz vinegar and 12 oz oil.
