Solve the problem.The average ticket price for an event held at the concert hall of a certain town can be modeled by 
where p(t) is the average price of a ticket t years after the concert hall opened. Find the linearization P1(t) of p at 
Then use this linearization to estimate the price of a ticket 14 years after the hall opened, and compare this to the value given by the model.
A. P1(t) = 5.11t - 5.91 P1(14) = $65.92; p(14) = $65.63 B. P1(t) = 5.11t - 6.2 P1(14) = $65.34; p(14) = $65.63 C. P1(t) = 5.11t + 39.04 P1(14) = $110.58; p(14) = $110.87 D. P1(t) = 7.54t - 6.2 P1(14) = $99.36; p(14) = $99.65
