Question

A share of ABC stock was worth $70 in 2011 and only

worth $38 in 2016. What is the equation for the
situation?

Answer 1

5v + 32y = 350

Explanation:

Let, the year counting starts in 2011 and represented by y.

So, the share of ABC stock value was $70 at y = 0. And in the year 2016 i.e. y = (2016 - 2011) = 5, the share worth $38.

If there is a linear relationship between the number of years since 2011 i.e. y and the value of the share of ABC stock i.e. v, then we can write the equation of this situation as

`(v - 70)/(70 - 38) = (y - 0)/(0 - 5)`

⇒ 5v - 350 = - 32y

⇒ 5v + 32y = 350 (Answer)
