Question

An investment is currently worth 2.125×104 dollars . Ten years ago, the investment was worth ​ 1.25×103 ​ dollars. How many times greater is the value of the investment today than the value of the investment ten years ago?

Answer 1

T = (2.125 x 10^4) / (1.25 x 10^3)  

T = 21,250 / 1,250  

T = 17  

Here we can notice a couple changes in the investment over the years.

1. The investment is 17 times the prior investment.  

2. The current amount is 16 times greater than the prior.
