Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:
Given the logarithm function

For logarithmic equations,
is equivalent to
such that
and 
In current case:



Substituting the values of
and
into the equation 

Percentage of Lemonade = 100 - (15 + 5)
= 100 - 20 = 80%
Now, We have to calculate the 80% of total amount of the drink i.e., 300 ml
So, 300 * 80%
= 300 * 0.80 [ 80% = 0.80 ]
= 240
In short, Your Answer would be: 240 ml
Hope this helps!
