Question

martha buys a leaf blower priced at $86. if the sales tax is 9%, what will be the total cost including tax?

Explanation:

Step1: Calculate the tax amount

The tax rate is 9%, which is 0.09 in decimal. The price before tax is $86. So the tax amount is $86 * 0.09.
$86\times0.09 = 7.74$

Step2: Calculate the total cost

Add the tax amount to the original price. So total cost = $86 + 7.74$.
$86 + 7.74 = 93.74$

Answer:

93.74
