Final answer:
To calculate the sales tax on a $30 pair of dress pants with a tax rate of 6.9%, convert the percentage to a decimal (0.069) and multiply by the price. The sales tax is $2.07, making the total cost $32.07 including tax.
Step-by-step explanation:
The question asks us to calculate the amount of sales tax for a pair of dress pants that is on sale for $30 with a sales tax rate of 6.9%. To find the amount of sales tax, we first convert the percentage to a decimal by dividing by 100, so 6.9% becomes 0.069. Then, we multiply this decimal by the original price of the item to determine the sales tax. So, the calculation is $30 × 0.069, which equals $2.07.
Therefore, the sales tax on a pair of dress pants costing $30 at a tax rate of 6.9% is $2.07. To find the total cost of the pants including sales tax, we add the original price of the pants to the sales tax: $30 + $2.07 = $32.07. Hence, the total cost of the pants including tax is $32.07.
