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.

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
