Ngozi earns $24000 in salary in the first year she works as an interpreter. each year, she earns a 3.5% raise. write a function that ngozi's salary s(t) in dollars, t years after she starts to work as an interpreter

Given that the current salary for Ngozi is $24000 and she earns 3.5% raise yearly, the function that will represent her salary in t years will be:
A=P(1+r)^t
where:
A=future amount
P=principle
r=rate
t=time 
thus plugging in the values we shall have:
s(t)=24000(1+3.5/100)^t
s(t)=24000(1.035)^t
thus the answer is:
s(t)=24000(1.035)^t

221,500 is the answer
