question 1
From 1985 to 2000 the percent p of total music sales with a certain format is modeled by p=5.7t - 11,308 where t is the year.
(a) evaluate p for t= 1985 and t =2000
(b) use your results from part to graph the equation from 1985 to 2000
(c) in what year was p = 74.9%?
(a) p = for t = 1985 round to the nearest tenth as needed
P = for t = 2000 round to the nearest tenth as needed
