Question 984122: 2. The value of a 2003 Toyota Corolla can be modeled by the linear equation V=-1402T+17600, where V is the value in dollars and T is the time in years after 2003.
a. Use the equation to predict what the value of the Corolla would be in 2009. (3 points)
b. In what year would you predict the value of the Corolla to be $7080? (3 points)
c. Based on this model, what was the cost of a brand new Corolla?
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! T=6 in 2009
T=0 when new
So, when NEW, it is $17,600.
When T=6, V=-8412+17,600 ;;;6*1402=8412
V=$9,188.
V=7080=-1402T+17,600
subtract 17,600 from both sides
-1402T=-10520
T=7.50 years, or mid 2011, between 7th and 8th years.
