Jonas performed an experiment for his science fair project. He learned that rinsing lettuce in vinegar kills more bacteria than rinsing with water or with a popular commercial product. As a follow-up to his project, he wants to determine the percentage of bacteria killed by rinsing with a diluted solution of vinegar. a. How much water and how much vinegar should be mixed to produce 10 cups of a mixture that is 40% vinegar?b. How much pure vinegar and how much 40% vinegar solution should be mixed to produce 10 cups of a mixture that is 60% vinegar?
