Need help with #11! Thanks :))

  57

Step-by-step explanation:

In terms of weeks, the exponential equation for population can be written as ...

  P(t) = P(0)·2^(t/6) . . . . . . the multiplier is 2 every 6 weeks

For the given initial population, P(0) = 9, we have ...

  P(t) = 9·2^(t/6)

__

For t = 112 days, we need to convert to weeks.

  t = (112 days)/(7 days/week) = 16 weeks

Then ...

  P(16) = 9·2^(16/6) ≈ 57.146

The population in 112 days is about 57 rabbits.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
