Answer 1

The correct responses are B (1 + 0.085)D and C 1.085D.

Option B is correct because it represents the price of the item (D dollars) plus the added tax (8.5% of D dollars).

Option C is also correct because the total cost of the item includes the price of the item (1D) and the tax (.085D).

Both expressions would give the same result: the cost of the item after tax.
