The total bill for a dinner advertised at $60 with an 18% tax is?

• A. $68.00
• B. $70.80
• C. $65.00
• D. $78.60

Answer: (B)

To find the total bill for the dinner, you first need to calculate the amount of tax applied to the advertised price of $60. The tax rate is 18%, so you can calculate the tax by multiplying the price by the tax rate expressed as a decimal.

First, convert the percentage to a decimal:

18% = 0.18

Next, calculate the tax amount:

Tax = Price × Tax Rate

Tax = $60 × 0.18 = $10.80

Now, to find the total bill, you add the tax to the advertised price:

Total Bill = Price + Tax

Total Bill = $60 + $10.80 = $70.80

This gives you the total bill after including the tax. Thus, the appropriate choice is the one that reflects this total. The calculated total of $70.80 includes the base price and the added tax, ensuring that the final amount reflects the full cost of the dinner.
