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
