does anyone know how to do this

from 1985 to 2000, The percent P of total of music sales with a certain format is modeled by P=5.9t – 11,706, where t is the year.

(A) Evaluate P for t =1985 and t=2000
(B) Use your results from part (a) to graph the equation from 1985 to 2000

(C) In what year was P = 76.3%?

(A) P= ? for t=1985 Round to the nearest tenth as needed

P= ? for t = 2000 Round to the nearest tenth as needed
