SOLUTION: The total amount spent by Americans on shoes and clothing from 2000 to 2009 can be modeled by
f(x)=49.79x2+71.73x+97.29
where x=0 represents 2000 and f(x) is in b

Question 1029934: The total amount spent by Americans on shoes and clothing from 2000 to 2009 can be modeled by
f(x)=49.79x2+71.73x+97.29
where x=0 represents 2000 and f(x) is in billions of dollars. Based om this model, in what year did spending on shoes and clothing reach a maximum?
The 49.79x2 is supposed to be x squared.
You can put this solution on YOUR website! : The total amount spent by Americans on shoes and clothing from 2000 to 2009 can be modeled by
f(x)= -49.79x2+71.73x+97.29
where x=0 represents year 2000 and f(x) is in billions of dollars. Based om this model, in what year did spending on shoes and clothing reach a maximum?
-----------------
Max occurs when x = -b/(2a) = -71.73/(2*-49.79) is less than one.
