Question

You are given the dollar value of a product in 2008 and the rate at which the value of the item is expected to change during the next 5 years. Use the information V of the product in terms of the year t. (Let t=8 represent 2008.)
The 2008 value is $12,500 and the rate is $850 increase per year.

Answer 1

so the equation is

V = 350t + 12500

just substitute t = 5 to find the value in 5 years time

Answer 2

V= $12,500
12,500= 850(8)x
12,500= 6800
subtract 6800 on both sides and you get 5700.
the equation is V= 850t + 5700
