Final answer:
To calculate the total price of a desk with sales tax, the sales tax percentage is converted to a decimal and multiplied by the item's price, then added to the original price, resulting in a total price of $63.45.
Step-by-step explanation:
To find the total price of a desk that costs $60 with a sales tax rate of 5.75%, we must first convert the tax rate into decimal form and then multiply it by the cost of the item.
First, convert the percent to a decimal: 5.75% = 0.0575.
Next, calculate the sales tax amount: $60 × 0.0575 = $3.45.
Finally, add the sales tax to the original price to determine the total price: $60 + $3.45 = $63.45.
Therefore, the correct total price of the desk, including sales tax, is $63.45, which corresponds to option d.
