the number of alcohol related traffic fatalities in the unit

the number of alcohol related traffic fatalities in the united states in 2003 was 17,524. for the next 8 years fatalities decreased at the rate of 797 per year. A) write a linear equation that describes the number of fatalities in terms of years after 2003. B) then use your equation to estimate the number of fatalities in 2012. C) determine the first year in which fatalities are likely to be less then 7,000 if the trend continues.

Solution

equation will be f(y)=17524-797*y where y = years after 2003

y(2012)=17524-9*979=10351

3.

7000=17524-797*y

hence y=13.20 means after 2003+20 = 2023

in year 2023.. fatalities will be under 7,000
