If a unit costs $14.00 and the sales tax is 6 percent, what is the total for 4 units?

• A. 56.00
• B. 59.36
• C. 65.00
• D. 66.40

Answer: (B)

To solve this, multiply the unit price by the quantity to get the pre-tax subtotal, then apply sales tax to that subtotal. Four units at $14 each cost 14 × 4 = 56.00 dollars before tax. A 6% tax means multiplying by 0.06: 56.00 × 0.06 = 3.36 dollars in tax. Add that tax to the subtotal: 56.00 + 3.36 = 59.36 dollars. So, the total is 59.36. The other totals would come from omitting tax or misapplying the rate, but the correct approach includes tax on the full pre-tax amount.
