Question

Three years ago, Jolene bought $750 worth of stock in a software company. Since then the value of her purchase has been increasing at an average rate of 12.60 per year. How much is the stock worth now?

Answer 1

`y = 12.6x + 750 \\ y = 12.6*3 + 750 \\ y = 787.80`

Answer 2

2017- 3 = 2014
she already had $750 in 2014.
12.60 x 3 = 37.8
750 + 37.8 = 787.8

Jolene now has $787.8

hope it helps!
