In order to calculate the amount, we simply substitute the number of years into x in both equations. After 3 years: f(3) = 5(3) + 150 = $165 g(3) = 150 * 1.03⁽³⁾ = $163.90 After 10 years: f(10) = 5(10) + 150 = $200 g(10) = 150 * 1.03⁽¹⁰⁾ = $201.59 After three years, the first account has more money but after ten years, the second account has more money.
