Answer 1

Answer:

10000

qed

Step-by-step explanation:

let say price was 100x two year before

increase  after 1 year = (9/100)*100x = 9x

price after 1 year = 100x + 9x = 109x

increase after 2nd year = (9/100)(109x) = 9.81x

price after 2 year = 109x + 9.81x = 118.81x

118.81x = 11881

x = 100

price of land 2 year ago was assumed to be 100x

so 100x = 100*100 = 10000
