    Exclamation functions AAAAAAAAHHHHHHH!

    The production in board feet and the cost of manufacturing lumber at a sawmill are P(h)=300h and C(n)= 0.2n+9000 where P(h) is the number of board feet that can be produced in h hours and C(n) is the cost of producing n borafd feet. Find C of P of h and interpret its meaning.
    This is what I have so far:
    C(300h)= 0.2(300h) +9000
    = 60h +9000
    HELP!!!!!!!!

    C(P(h)) = 60h + 9000

    y = mx + b
    This is a linear function. So what can you say about the "C" intercept, when h = 0 (this equation's version of a y-intercept)? What can you say about the slope? (In this case 60).
