Answer: Option 'd' is correct.
Step-by-step explanation:
Since we have given that
Number of hours of pop music = 3
Number of hours of classical music = 2
According to question, Every month onwards, the hours of pop music in her collection is 5% more than what she had the previous month. Her classical music does not change.
Rate of increment = 5% = 0.05
Let the number of months be 'x'.
So, our required function becomes,

Hence, Option 'd' is correct.
I believe the given should be written as,
(8.6 x 10^8) ÷ (3.2 x 10^3)
By directly solving the expression, we obtain an answer of
268750
Which can also be written as 2.6875 x 10^5. Thus, the answer to this item is letter B.
