Sagot :
Step-by-step explanation:
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)

Answer:
ABC table
