Question 896594: You are given the dollar value of a product in 2013 and the rate at which the value of the product is expected to change during the next 5 years. Use this information to write a linear equation that gives the dollar value V of the product in terms of the year t. (Let t = 13 represent 2013.)
2013 Value Rate
$2700 $135 decrease per year

Well here t should be a variable. Lets think this starts from year 2000 which makes t = 0. And find the value of it in 2000. Think it's then value is C.
V = C - 135t
In 2013 t=13
2700 = C - 135*13
2700 + 135*13 = C (it's value in 2000)
4455 $ = C
So lets make equation. t = {Z+}
V = 4455 - 135t
V = 135*(33-x)
