The number of cases of unruly passenger behavior on board aircraft was 339 in 2007, and it increased by about 1346 cases per year until 2013 (Source: International Air Transport Association). Let n be the number of cases of unruly passenger behavior in the year that is t years since 2007.
a. Find an equation of a linear model to describe the situation.
b. Solve the equation you found in part (a) for t.
c. Use the equation you found in part (b) to estimate in which years there were 3000, 4500, 6000, 7500, and 9000 cases of unruly passenger behavior.
