53,760,970 households/year

Step-by-step explanation:

First step is to do 65,929,420 - 12,168,450 = 53,760,970

Now divide 53,760,970 by 20 since the difference in 1997 and 1977 is 20

53,760,970/20 = 2,688,048.5

So each year 2,688,048.5 people got cable.

But it would be 53,760,970/year because then you could divide it by how ever many years to see how many people got cable.

Hope this helps!!
