Q. Ngozi earns $24,000 in salary in the first year she works as an interpreter. Each year, she earns a 3.5% raise.Write a function that gives Ngozi's salary S(t), in dollars, t years after she starts to work as an interpreter. Do not enter commas in your answer.S(t)=
Identify Salary and Raise: Identify the initial salary and the annual raise percentage.Ngozi's initial salary is $24,000, and she receives a 3.5% raise each year.
Convert to Decimal: Convert the annual raise percentage to a decimal.To convert a percentage to a decimal, divide by 100.3.5% as a decimal is 3.5/100=0.035.
Write Salary Function: Write the function for Ngozi's salary after t years.Ngozi's salary after t years can be represented by an exponential growth function because she receives a constant percentage raise each year.The general formula for exponential growth is:Initial amount×(1+growth rate)timeSo, the function for Ngozi's salary S(t) is:S(t)=Initial salary×(1+raise rate)t
Substitute Initial Values: Substitute the initial salary and the raise rate into the function.S(t)=24000×(1+0.035)tThis is the function that represents Ngozi's salary t years after she starts working as an interpreter.
