Question

If someone could help me with this i would greatly appreciate it. A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is 60% salt and Solution B is 85% salt. She wants to obtain 40 ounces of a mixture that is 70% salt. How many ounces of each solution should she use?

Answer 1

you divide 40 by 70. then get 1.75 then times 1.75 by A and B which would be 60 * 1.75 = 105 so that means she has 105 ounces for A and for B do the same thing, 85 * 1.75 = 148.75 for B.  :D i would like brainliest plz this took a lot of my time (also stay safe!!!)
