The problem is to write a program that will read some data from the keyboard, build a $2-$dimensional list with that data, process the data and report the results. The input data represents one shift at John Emerald's Steakhouse, the output results will help management make improvements to customer service and worker satisfaction.

Initialization and standard input:

$-$ Your program must process all the data given by the user; you do not know how much will be entered. The program should work for any amount of input data, not just the specific values in the examples.

$-$ The first two inputs provide management with some key business metrics regarding the number of tables served $($integer$)$ and the total receipts collected from those tables $($ float $).$

Worker input, wage list creation $($ Sentinel Logic $)$:

$-$ The inputs from the user from the keyboard contain a worker name $($with no spaces in it$)$ then a comma then two numbers separated by commas $($which represent the hours worked and the hourly wage of that worker$).$ The numbers will be floats. There may or may not be whitespace around the numbers.

$-$ The user stops inputting by pressing Enter alone.

$-$ Your program builds a $2-$dimensional list where each row represents one worker. Each row contains the worker wages $($hours worked $*$ hourly wage$)$ in the first column and the worker's name in the second column

$-$ One row of wage list $=[$ worker wages, worker name $]$

$-$ Sample of a $2$D list: $[[45.,$ 'Becca' $],[59\mathrm{.}50$ 'Adam' $],...]$

Output of the results:

$-$ The wages received by each worker formatted to $2$ decimal places and the worker's name, reverse sorted by the wages received.

$-$ Estimates the food cost as $\backslash (35\backslash \%\backslash )$ of total receipts

$-$ Totals the wages of all workers for the Labor cost $($ Total shift pay $)-$ requires an accumulator in one of your loops

$-$ The Gross Profit $($ Total receipts $-$ Food Cost $-$ Labor Cost $)$

$-$ The Gross Profit per Table Served
