Question 178885
so we have 10 years between 1990 and 2000
:
we must find the increase per year.
:
since the increase is 350 cars over 10 years we just divide that by number of years which is 10
:
350/10=35
:
so lets call S the number of cars sold and it is a function of time t
:
{{{highlight(S(t)=35t+650)}}}........so our beginning year is 1990 and in that year they sold 650
:
cars.
:
year 2004 would be 14 year or t=14
:
{{{S(14)=35(14)+650=490+650=highlight(1140)}}}estimated cars sold in 2004
