(1) The cable company installed three cable outlets in the Horace family home. Total cost=$30+$20*3. Sufficient.

(2) The amount that the cable company charged the Horace family for installing cable television in their home was equivalent to an average (arithmetic mean) charge of the $30 per cable outlet installed. Say the number of outlets is x, then Total cost=$30+$20*x and the average is ($30+$20*x)/x --> ($30+$20*x)/x=30. We can solve for x. Sufficient.

Answer: D.

The amount charged = 30+20x, where x is the number of outlets installed
statement (1) gives the value of 'x' such that it alone is sufficient.
statement (2) implies that (30+20x)/x = 30, from which x can be found out and the amount charged as well. statement (2) alone is sufficient
