Question

Writing a linear equation

You are given the 2012 value of a product and rate at which the value is expected to change during the next 5 years. Use this information to write a linear equation that gives the dollar V of product in terms of the year.
(Let t=12 represent 2012).

2012 value
$156
Rate
$4.50 increase per year

Answer 1

V = 156 + 4.5 (t - 12)

Answer 2

201

Answer 3

You are given the 2012 value of a product and the rate at which the value 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. (Let
t = 12
represent 2012.)
2012 Value Rate
$235,000 $5500 increase per year

Answer 4

235,000=5,500(12)+b
b=235,000-5,500(12)=169,000
V(t)=5,500(t)+169,000
