Analysis
1. Use the formula for exponential decay:
The formula for calculating the remaining quantity after time periods with a decay rate (expressed as a decimal) starting from an initial quantity is .
In this case:
The initial number of rabbits is .
The decay rate is , which in decimal form is .
The number of months is .
2. Substitute the values into the formula:
