Masteriza [31]

Answer:

The present value after 2 years is $98

Explanation:

Given

$a = 200$

$r = 30\%$

$t = 2$

Required

Determine the new value

This is calculated using:

$y = ab^t$

Where b =

$b = 1 - r$

This gives:

$b = 1-30\%$

$b = 1-0.30$

$b = 0.70$

So:

$y = ab^t$

$y =200 * 0.70 ^2$

$y =98$

<em>The present value after 2 years is $98</em>
