Brainliest answer gets the mark. plus 20 ptsa scientist has two solutions, which she has labeled solution a and solution b. each contains salt. she knows that solution a is 70 % salt and solution b is 95 % salt. she wants to obtain 120 ounces of a mixture that is 85 % salt. how many ounces of each solution should she use?

Let x = the number of ounces of Solution A

Let y = the number of ounces of Solution B

x + y = 180        y = 180 - x

.60x + .85y = .75(180)

.60x + .85y = 135      Multiply both sides of the equation by 100 to remove the decimal points.

60x + 85y = 13500

60x + 85(180 - x) = 13500

60x + 15300 - 85x = 13500

-25x = -1800

x = 72ounces

y = 180 - 72

y = 108 ounces
