Answer:
4th option
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= - (3x² - 3x - 5)
= 4x² - 3x² + 3x + 5 ← collect like terms
= x² + 3x + 5
x = volume of 10% solution to use in the mixture
y = volume of 25% solution to use
She wants a 200 mL solution, so x + y = 200.
The first solution contributes 0.10x mL of alcohol, while the second contributes 0.25y mL. Together, they make a solution with 0.20(x + y) = 0.20(200) = 40 mL of alcohol.
