Answer (3)
We will calculate the amount spent of each of six persons assuming they spent money at each of three tables (A,B,C) to arrive at a table shown in the attached image.
For example, Arielle bought 10 items at table A with a change of $6.50, so amount she had to spent if she bought at table A was 10*1.25+6.50=$19.00 (see table, top left corner).
We repeat the same exercise for all of the amount spent of each person at each table to complete the table in the given image.
There is only one amount that is common to all of them, namely $20.
Scanning down the columns, we see that only
Erik spent at table A,
Arielle, Denise and Salena spent at table B,
Brayden and Tommy spent at table C.
So out of the choices, those who spent at the same table are:
Salena and Arielle (table B)
Brayden and Tommy (table C) ;
The people that spent at the same table are;
Salena and Arielle who both spent at Table B
Brayden and Tommy who both spent at Table C
What is cost table?
A** cost** that is incurred when a group of products or services are produced, and which cannot be identified to specific products or services within each group.
here, we have,
to Solve Cost Table :
We will calculate the amount spent of each of six persons assuming they spent money at each of three tables (A,B,C) to arrive at **a table **shown in the attached image.
For example, Arielle bought 10 items at table A with a change of $6.50, so amount she had to spent if she bought at table A was;
10*1.25 + 6.50 = $19.00 (see table, top left corner).
We repeat the same exercise for all of the amount spent of each person at each table to complete the table in the given image.
There is only one **amount **that is common to all of them, namely $20.
Scanning down the columns, we see that only;
Erik spent at table A,
Arielle, Denise and Salena spent at table B,
Brayden and Tommy spent at table C.
So out of the choices, those who spent at the same **table **are:
Salena and Arielle (table B)

The people who bought items from the same table are Brayden and Denise, who both purchased from Table B. Other combinations include Salena buying from Table B and Erik and Tommy buying from Table C. So the answer is option E: Brayden and Denise.
