Question

A business traveler buys a round-trip plane ticket for $629. The tax rate is 7.5%. How much was the cost after tax? Round to the nearest cent if necessary.

$____

Answer 1

To find the total cost after tax for a $629 plane ticket with a 7.5% tax rate, convert the tax rate to a decimal and multiply it by the ticket cost. Add this tax to the original ticket cost and round to the nearest cent, resulting in a final total of $676.18.

Step-by-step explanation:

The question asks us to calculate the total cost of a plane ticket after tax is added. The ticket cost is $629, and the tax rate is 7.5%. To find the total cost after tax, convert the tax rate from a percentage to a decimal by dividing by 100, which gives us 0.075. Then, multiply the ticket cost by the decimal tax rate to find the amount of tax.

Tax amount = $629 × 0.075 = $47.175

To find the total cost after tax, we add the tax amount to the original ticket cost:

Total cost after tax = $629 + $47.175 = $676.175

Now we round the total to the nearest cent, giving us a final total of $676.18.
