15*4= 60 (60 students in total)
180/60= 3 (180 book covers divided among 60 students)
Each student gets 3 covers.<span />
Since we know f(x)=11 all we need to do is substitute and solve. so
11=-2x+3 subtract 3 from both sides
8=-2x divide both sides by -2
-4=x
sub back in to check
-2(-4)+3=8+3=11 looks good
