Full solution

Q. Ngozi earns $24,000 \$ 24,000 in salary in the first year she works as an interpreter. Each year, she earns a 3.5% 3.5 \% raise.\newlineWrite a function that gives Ngozi's salary S(t) S(t) , in dollars, t t years after she starts to work as an interpreter. Do not enter commas in your answer.\newlineS(t)= S(t)=
  1. Identify Salary and Raise: Identify the initial salary and the annual raise percentage.\newlineNgozi's initial salary is $24,000\$24,000, and she receives a 3.5%3.5\% raise each year.
  2. Convert to Decimal: Convert the annual raise percentage to a decimal.\newlineTo convert a percentage to a decimal, divide by 100100.\newline3.5%3.5\% as a decimal is 3.5/100=0.0353.5 / 100 = 0.035.
  3. Write Salary Function: Write the function for Ngozi's salary after tt years.\newlineNgozi's salary after tt years can be represented by an exponential growth function because she receives a constant percentage raise each year.\newlineThe general formula for exponential growth is:\newlineInitial amount×(1+growth rate)time\text{Initial amount} \times (1 + \text{growth rate})^{\text{time}}\newlineSo, the function for Ngozi's salary S(t)S(t) is:\newlineS(t)=Initial salary×(1+raise rate)tS(t) = \text{Initial salary} \times (1 + \text{raise rate})^t
  4. Substitute Initial Values: Substitute the initial salary and the raise rate into the function.\newlineS(t)=24000×(1+0.035)tS(t) = 24000 \times (1 + 0.035)^t\newlineThis is the function that represents Ngozi's salary tt years after she starts working as an interpreter.
