From the table, we can observe that the formula for the total cost of item is
[tex]\text{Total cost of item = Cost of item + Tax on item}[/tex]
From the data in the table, cost of item 6.00 has the input incorrect because the sum of the cost of its item and tax on the item is,
[tex]\text{Total cost of item=6.00+56=6.56}[/tex]
but the total cost was incorrectly inputed as 7.56.
Hence, the correct option is Option A.
