So 30 + 3(20)= 90. Sufficient, Stmt2: the amount that the cable company charged the Horace family for installing the Cable television in their home was equivalent to an average charge of$30 per cable installed.

Let the cable company installed "x" cable outlets in the Horace Family home.
So total= 30 +x(20)

Average of total amount = 30+x(20) / x = 30
x=3

Total amount = 30 + 3(20) = 90 Sufficient,

To install cable television in a home, a certain cable company charges a basic fee of $30 plus a fee of$20 for each cable outlet installed in the home. How much did the cable company charge the Horace family for installing cable television in their home?

(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.
