Total box office receipts (in millions of dollars) declined from 2002 to 2006.The receipts in year x can be approximated by y=-73.40x+9598.9 where x=2 corresponds to 2002. Assume this equation remains valid through 2012. a) estimate the box office receipts in 2006 b) In what years will the box office receipts be $9 billion?

Solution

a)

Y = -73.40 * 6 + 9598.9

Y = 9158.5

b)

9000 = -73.40*x + 9598.9

x = 8.16

x = 9
