Answer:
a. Let's call the average ticket price for Dallas in 2005 as "d" and the average ticket price for Boston in 2005 as "b". Then the system of equations can be written as:
y_d = d + 0.53x (where y_d represents the price of an average ticket for Dallas after x years)
y_b = b - 1.08x (where y_b represents the price of an average ticket for Boston after x years)
b. To find the number of years in which the average ticket price for Dallas will approximately equal that of Boston, we need to solve the equation y_d = y_b for x. Plugging in the equations for y_d and y_b, we get:
d + 0.53x = b - 1.08x
Rearranging and solving for x, we have:
1.61x = b - d
x = (b - d) / 1.61
Now we just need to plug in the values for d and b from the table:
d = 53.60
b = 55.93
x = (55.93 - 53.60) / 1.61 = 2.33 years
So it will take approximately 2.33 years for the average ticket price for Dallas to approximately equal that of Boston.
