Final answer:
To calculate the sales tax on an item at a 4% rate, convert 4% to 0.04 decimal form and multiply by the item's price. For a $150 item, the sales tax would be $150.00 × 0.04 = $6.00.
Step-by-step explanation:
The question relates to the calculation of sales tax on an item. To find the sales tax, you need to first convert the percent to decimal form. In this case, the sales tax rate is 4%, so you would convert this to 0.04 in decimal form.
Next, you multiply the decimal sales tax rate by the cost of the item to determine the amount of sales tax. For instance, if an item costs $100.00, the calculation would be $100.00 × 0.04 = $4.00 in sales tax. You then add this sales tax to the original price to obtain the total cost.
The question refers to an item with a missing price value. However, assuming you meant to include a specific price, such as $150.00, you would perform the calculation as follows: $150.00 × 0.04 = $6.00. Thus, the sales tax on a $150.00 item with a 4% sales tax rate would be $6.00.
