y= -49.2x + 1756.7

0= -49.2x + 1756.7

-1756.7 = -49.2x

-1756.7 / -49.2 = -49.2x / -49.2

x = 35.705 We will round down the result so

**x = 35**When x=35 that is 35 years after 1997. The year in which the average annual number of cigarettes smoked is zero is

**1997 + 35 = 2032****The answer is 2032**
