Final answer:
To determine the total bill of an airline ticket with a 7% tax on a $210 ticket, multiply the ticket cost by 0.07 to find the tax amount ($14.70), and then add it to the ticket cost, resulting in a total of $224.70.
Step-by-step explanation:
To calculate the total bill for an airline ticket costing $210 with a 7% tax rate, first calculate the amount of the tax by converting the percentage to a decimal and then multiplying by the ticket cost. The formula to find the tax amount is:
Amount of tax = ticket cost × tax rate (in decimal form)
Therefore, the amount of tax is:
$210 × 0.07 = $14.70
The total bill for the ticket, including tax, is:
$210 + $14.70 = $224.70
