Answer:
- 24 ounces of solution B
- 16 ounces of solution A
Step-by-step explanation:
The largest contributor of salt to the mix is the 45% solution (B), so we'll let our variable (b) represent the quantity of that. The total amount desired is 40 ounces, so the quantity of solution A is (40-b) ounces. Then the amount of salt in the mix is ...
0.45b +0.20(40-b) = 0.35(40)
Simplifying and subtracting 0.20(40), we get ...
0.25b = 0.15(40)
b = 40(.15/.25) = 24
(40-b) = 16
The scientist should use 24 ounces of Solution B and 16 ounces of Solution A.
