Tyler's online custom longbow sales business has been running its social media marketing campaign for 2 years. The marketing company predicted that sales would increase by 10% per year. Tyler found that the prediction has been close. His sales were $3.5 million per year when he started the campaign. If the growth continues, he can model his future sales with the function S(t)=3.5(1.1)t million The annual sales, S, is a function of t, the total time in years that Tyler runs the campaign. If the company's prediction holds true, what will Tyler's annual sales be (in millions) after running the campaign for 5 years?
