Question

the cost of a mission decrease every year by 10% if the present cost of the mission is 10000 find the cost after 2 years

Answer 1

Answer:

The answer could be 8100.

Step-by-step explanation:

In year 1,

The cost of mission is 10,000.

It decreases by 10%, which means it will decrease by 10% of 10,000. Hence , it will decrease by 1000 and be 9000.

In year 2,

The cost of mission is 9000.

It decreases by 10%, which means it will decrease by 10% of 9,000. Hence, it will decrease by 900 and be 8100.

Answer 2

Step-by-step explanation:

p= 10000

n= 2year

r=10%

price is decreasing so,

A=p(1-r/100)ⁿ

= 10000(1-10/100)²

= 10000(1-1/10)²

= 10000(9/10)²

= 10000×81/100

= 8100

hence price aftwr 2 year is 8100
