Every year, the value of a condonium in Singapore appreciates by 15% of its value of the condonium was $899300 in 2012, find it's value in 2010

The value of a condonium in 2010 is 680000.

Step-by-step explanation:

It is given that the value of a condonium in Singapore appreciates by 15%.

Value of the condonium in 2012 =  $899300

The general exponential growth function  is

         .... (1)

where, a is initial value, r is growth rate and t is time in year.

In the given problem,

Initial year = 2012

Initial value = $899300

Growth rate = 15% = 0.15

Substitute a=$899300 and r=0.15 in equation (1).

         ... (2)

We need to find the value of a condonium in 2010.

Substitute t=-2 in equation (2).

Therefore, the value of a condonium in 2010 is 680000.
