Simple Interest
Simple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:
[tex]A(t) = A(0)(1 + rt)[/tex]
In which:
- A(0) is the initial amount.
- r is the interest rate, as a decimal.
In this problem, considering the time from the beginning of 2018, and the interest rate of r = 0.11, his salaries for each year are given by:
[tex]A(1) = 17.1[1 + 0.11(1)] = 18.981[/tex]
[tex]A(2) = 8.9[1 + 0.11(2)] = 10.858[/tex]
[tex]A(3) = 7.5[1 + 0.11(3)] = 9.975[/tex]
[tex]A(4) = 8.25[1 + 0.11(4)] = 11.88[/tex]
[tex]A(5) = 8.25[1 + 0.11(5)] = 12.7875[/tex]
Hence, his salaries are as follows:
- $18.981 million in 2018.
- $10.858 million in 2019.
- $9.975 million in 2020.
- $11.88 million in 2021.
- $12.7875 million in 2022.
