You would add both totals since they said how much was the bill includingall the totals. So $192.77+ 48.19= 240.96
Since there is 12 people that need to chip in each, you would divide that total by 12.
240.96/12 = $20.08 each person would have to pay
Hope this helped!
2x-y=1 is also equal to y=2x-1 so then plug in 1 or x and so on to create a table
It would be = because they shipped the same amount in each year
