An article retails for 27.50. The city sales tax is 6%, and the federal excise tax is 8%. How much does the article cost altogether?

Cost of the article = $27.50

Amount of city sales tax = (27.50 x 6%) = $1.65

Amount of excise tax = (27.50 x 8%) = $2.20

From my knowledge, we pay city sales tax and federal excise tax when we buy something, so the total cost would be $31.35
