Each dataset consists of twelve lines. Each line would contain the closing balance of his bank account for a particular month. Each number is positive and displayed to the penny. No dollar sign would be included.

Output

For each dataset, you should generate one line of output with the following values:the dataset number as a decimal intege R (start counting at one), a space, a character '$', and a single number, the average (mean) of the closing Balan Ces for the twelve months. It'll be rounded to the nearest penny.

note:used comma (,) toseparate the thousands.

Sample Input

1 100.00 489.12 12454.12 1234.10 823.05 109.20 5.27 1542.25 839.18 83.99 1295.01 1.75

Sample OUTPUT1 $1,581.42
HINT
