4. The daily cost of production (in dollars) for Jimbo's Cheesy Bread Bakery is given by the function $C(x) = 0.25x^2 - 40x + 2100$, where $x$ is the number of packets sold daily. Each packet is sold for $10, so the revenue (in dollars) is given by the function $R(x) = 10x$. (a) Find the formula for Jimbo's daily profit $P(x)$. Compute $P(50)$, and interpret its meaning. Hint: PROFIT = REVENUE - COST. (b) Find the total number of packets that maximizes Jimbo's profit. Justify your answer.
