Answer:
8 Liters
Step-by-step explanation:
Percentage of Alcohol in water= 2L X 0 =0
Percentage of Alcohol to be added = xL X 0.9 =0.9x
- New Volume =(x+2) Liters
- Desired Concentration = 0.72%
Therefore:
0+0.9x=0.72(x+2)
0.9x=0.72x+1.44
Collect like terms
0.9x-0.72x=1.44
0.18x=1.44
Divide both sides by 1.44
x=8 Liters
Therefore, Shanice must add 8 Liters of 90% alcohol solution to create the desired mixture

2nd option
Step-by-step explanation:
Given
2x - 8y + 3x² + 7y - 12x ← collect like terms

= 3x² + (- 10x) + (- y)
= 3x² - 10x - y
