Answer:
27oz
Explanation:
Let the volume quantity of the 10% solution = x
The volume quantity of the 15% alcohol solution is known as = 18oz
Therefore the volume of the 12% product = 18oz + x
Therefore
0.10 × x + 0.15 × 18oz = 0.12 × (18oz+x)
0.15×18oz - 0.12×18oz = 0.12×x - 0.10×x
.
0.03*18oz = 0.02x
Dividing both sides by 0.02
x = 27oz
Verifying the answer, we have
0.1 × 27 + 18 × 0.15 = 0.12 × 45
2.7 + 2.7 = 5.4
