4 The number of window panes a
company can produce is a function of time
t, measured in hours of operation per day,
and is given by w(1) = 7+ - 3. The company's
profit $P is a function of the number of
windows sold, given by P(w) = 50w - 2000.
a Find the company's profit (or loss) if it
operates for 4 hours a day.
b Find the company's profit as a function of
time, expressed in the form P(t) = m + c
where m, CER.
Determine ihe number of hours (to
