Explanation / Answer

a) first quarter of 2010

x=5

number of total subscribers = 9.78*(1.07)5= 9.78*1.40 = 13.69 million

b) fourth quarter of 2012

x=16

number of total subscribers = 9.78*(1.07)16= 9.78*2.95 = 28.85 million

c) to find quarter and year for 25 million

25 = 9.78(1.07)x

25/9.78 = (1.07)x

2.55 = (1.07)x

(1.07)14 = (1.07)x

x=14

in the year 2012 and quarter 3(x=15), it will cross 25 million.
