This would be A because $100 is the initial amount, and you are adding the amount that arises after (d) days. Since you are adding, it will be the sum. B says product, so you can rule it out. D says difference, so you can rule that out as well. C would be adding the days, not the amount earned each day.
Using an exponential function, it is found that there will be 32,866 pigeons in 13 years.
<h3>What is an exponential function?</h3>
An increasing exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
The initial value and the growth rate are given by:
A(0) = 9520, r = 0.1.
Hence the function is given by:

Hence in 13 years, the amount of pigeons will be of:

Total deposit = 645.30 + 645.30 = $1290.60
Total withdrawals= 158.25 +168.36+157.42+148.46 = $632.49
Balance = 398.26 + 1290.60 - 632.49 = $1056.37
