Question

An investment is currently worth 2.125x10^4 dollars. Ten years ago, the investment was worth 1.25x10^3 dollars. How many times greater is the value of the same investment today's then the value of the investment 10 years ago

Answer 1

17 times

Explanation:

Let "x" be the number of times today's investment is more than the investment 10 years ago

Investment 10 years ago = 1.25*10^3 = 1,250

Investment today = 2.125*10^4 = 21,250

So, we can form the equation as shown below:

1250*x = 21,250

x = 21,250/1,250

x = 17

Therefore, today's investment is 17 times greater than the investment 10 years ago

Answer 2

17 times greater.

Explanation:

Given the current value of investment to be $2.125×10⁴

Ten years ago the investment worth = $1.25×10³

To know the number of times greater the value of the same investment today(current value) to the value of the investment 10 years ago, we will divide the current investment value by the value 10years ago i.e

Factor of increase = current investment/investment value 10years ago

Factor of increase = $2.125×10⁴/$1.25×10³

= $2.125/$1.25 × 10^4-3

= 1.7×10¹

= 17

This shows that the current has increase 17times the clue of the money 10years ago
