Write an exponential function to model the situation. The cost of tuition at a college is $12,000 and is increasing at a rate of 6% per year.

C(t) = 12000(.94)t

C(t) = 12000(1.94)t

C(t) = 12000(.06)t

C(t) = 12000(1.06)t

Write an exponential function to model the situation. You invest $1500. Your investment escalates at a rate of 3.5%.

B(t) = 1500(0.965)t

B(t) = 1500(1.035)t

B(t) = 1500(.035)t

B(t) = 1500(1.965)t
