Question

Kristina needs to mix a 20% alcohol solution with a 60% alcohol solution to create 200 milliliters of a 34% solution. How many milliliters of each solution must Kristina use?

Answer 1

Answer:

20% alc: 135 mL

60% alc: 65 mL

Explanation:

Table:

20% alc /  x  /    (.2)(x)        

60% alc /  200-x /   .6(200-x)        

34% alc. / 200 /   (.34)(200)        

Equation for 60% alc:   .6(200-x) = (.34)(200) + (.2)(x)

Equation for 20% alc:   (.2)(x) + .6(200-x) = (.34)(200)

Final:

20% alc: 135 mL

60% alc: 65 mL
