Answer: The inequality given is:
250(1.12)^s > 3750
We want to solve for s, the number of years until the number of mice exceeds 3750. We can begin by dividing both sides of the inequality by 250:
(1.12)^s > 15
Next, we can take the logarithm of both sides of the inequality with base 1.12:
log₁.₁₂ [(1.12)^s] > log₁.₁₂ (15)
s > log₁.₁₂ (15)
Using a calculator, we can evaluate the right-hand side to be approximately 6.27. Therefore:
s > 6.27
Since s must be a whole number, we can round up to the nearest integer to get:
s = 7
Therefore, in 7 years the number of mice will exceed 3750.
