Question 289708: A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. Combining 20 ounces of Solution A with 10 ounces of Solution B gives 30 ounces of a mixture that is 55% salt. Combining 50 ounces of Solution A with 100 ounces of Solution B gives 150 ounces of a mixture that is 65% salt.
What are the percentages of salt in the two solutions?
