Question 1127175: A new television depreciates
;$130 per year, and it is worth $290 after four years. Find a function that describes the value of this television, if x is the age of the television in years. Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! the depreciation is 130 per year.
after 4 years, the depreciation has become 4 * 130 = 520.
the train is worth 290 after 4 years.
let x = the original value of the train.
the equation becomes 290 = x - 520.
add 520 to both sides of this equation to get x = 810.
that should be the original value of the television.
810 - 130 * 4 = 810 - 520 = 290.
x is not the age of the television in years.
x represents the original value of the television.
you are given that the age of the television is 4 years.
it looked to me like you needed to solve for the original value of the television, so that's what i solved for.
