Apaint company decided to test its durability of its white paint. they painted a square all white with their paint and measured the reflectivity of the square each year. seven years after being painted, the reflectivity was 85%. ten years after being painted, the reflectivity dropped to 82.9% assuming that the reflectivity decreases steadily with time, write an equation that gives the reflectivity r (as a percentage) as a function of time t in years. what is the reflectivity of a fresh coat of white paint?
