Answer

Explanation:

Step1: Determine the time interval

From 7:00 a.m. to 10:00 a.m. is (h_1 = 3) hours, and from 7:00 a.m. to 1:00 p.m. is (h_2=6) hours.

Step2: Calculate the number of tickets at (h = 3) and (h = 6)

When (h = 3), (T(3)=\frac{386+110\times3}{3}=\frac{386 + 330}{3}=\frac{716}{3}\approx238.67) When (h = 6), (T(6)=\frac{386+110\times6}{6}=\frac{386+660}{6}=\frac{1046}{6}\approx174.33)

Step3: Calculate the rate of change

The rate of change formula is (\frac{T(h_2)-T(h_1)}{h_2 - h_1}). Substitute (h_1 = 3), (h_2=6), (T(3)\approx238.67), (T(6)\approx174.33) into the formula: (\frac{174.33 - 238.67}{6 - 3}=\frac{- 64.34}{3}\approx - 21)

Answer:

A. -21 tickets per hour
