Final answer:
To calculate the total cost of the cowboy hat including tax, multiply the price by the sales tax rate, round the result, and add it to the original price. The hat costs $44.57 after including the sales tax.
Step-by-step explanation:
To calculate the total cost of a cowboy hat priced at $41.95 with a sales tax rate of 0.0625, first, find the amount of sales tax by converting the percentage to a decimal. Multiply the price of the hat by the decimal form of the tax rate:
$41.95 × 0.0625 = $2.622.
Next, round the sales tax to the nearest penny, which gives us $2.62. Then add the original price of the cowboy hat to the sales tax:
$41.95 + $2.62 = $44.57.
Therefore, the total cost of the cowboy hat in Texas, including tax, is $44.57.
