Final answer:
To find the sales tax on a 63 item with an 8.8% tax rate, convert the percentage to a decimal (0.088), multiply by the item's cost to get 5.544, round to 5.54, and add to the original cost for a total of 68.54.
Step-by-step explanation:
To calculate the amount of sales tax for an item costing 63 with a sales tax rate of 8.8%, first convert the percentage rate to a decimal. To do this, move the decimal point two places to the left, making 8.8% become 0.088. Now, multiply the item's price by the decimal sales tax rate:
Amount of sales tax = 63 × 0.088
The sales tax would be:
5.544
After calculating the sales tax, round to the nearest hundredth, which is 5.54 in this case. To find the total cost, add the original item price plus the sales tax:
63 + 5.54 = 68.54
Therefore, the total cost of the item after including the sales tax would be 68.54.
