SnapAndSolve AI · Accepted Answer

Let x be the quantity of 71% solution needed. Then, the quantity of 18% solution needed will be (8877.5 - x) mL.

Set up the equation based on the concentration:

0.71x + 0.18(8877.5 - x) = 0.20 * 8877.5

0.71x + 1597.95 - 0.18x = 1775.5

0.53x = 177.55

x = 335.00

Answer: 335 mL
