Vinaigrette salad dressing consists maily of oil and vinegar. The density of olive oil is 0.918 g/cm, the density of vinegar is 1.006 g/cm, and the two do not mix. If a certain mixture of olive oil and vinegar has a total mass of 397.8 g and a total volume of 422.8 cm, what is the volume of the oil and what is the volume of the vinegar in the mixture?
Physics approach: ¦Ñv+¦Ñ(v-v) = m where ¦Ñ is the density of olive oil, ¦Ñ is the density of vinegar, v is the total volume, and m is the total mass of the mixture.
