Answer 1

You would expected 88,602 households to be watching Town Talk.

Explanation:

This question can be solved by a simple rule of three.

Of 103 households, 39 were watching Town Talk. Out of 234,000 households, how many were watching Town Talk?

103 households - 39 watching Town Talk

234000 households - x watching Town Talk

`103x = 39*234000`

`x = (39*234000)/(103)`

`x = 88,602`

You would expected 88,602 households to be watching Town Talk.
