Answer:
a
Step-by-step explanation:
1:4 is the answer to the question.
120 mL
If the 480 mL has 75% concentration, then 360 mL are alcohol. To turn the 360 into only 60%, you need to increase the amount of water.
Answer: 25%
Subtract 75% from 100%
100-75=25%
When x=0, y = ab⁰ = a
The y-intercept of the graph is 3, so a=3.
