Question: Use the Linear Approximation. When a bus pass from Albuquerque to Los Alamos is priced at p dollars, a bus company takes in a monthly

Use the Linear Approximation. When a bus pass from Albuquerque to Los Alamos is priced at p dollars, a bus company takes in a monthly revenue of R(p) = 1.5p − 0.01p2 (in thousands of dollars).
(a) Estimate ΔR if the price rises from $50 to $53.
(b) If p = 80, how will revenue be affected by a small increase in price? Explain using the Linear Approximation.
