can some one help me with 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

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