Question

Answer:

The first answer is After 9 months.
Since in the problem it states that "t months" in for b(t) and after plugging in a 9 that turns it into months.
The second answer is Number of unread books remaining is 30.
Since when plugging in 9 for t the equation changes and the new equation changes to 75-5(9) = 75-45 = 30.
I hoped I helped! Goodluck!
