Suppose a local vendor charges $2 per hot dog and that the number of hot dogs sold per hour is given by

(x) = −4t2 + 20t+ 76,t

wheretis the number of hours since 10 AM, 0 ≤≤ 4.t

(a) Find an expression for the revenue per hourRas a function ofx.

R(x) = 1

(b) Find and simplify (R)(x).t

What does this represent?

(c) What is the revenue per hour at noon?

I am just lost on this! Maybe my brain isn't processing it or something lol, but I have no clue.3
