You go shopping with a friend and end up buying a shirt for $23.90, a pair of pants for $34.50 and some socks for $3.65. If sales tax is 7.5%, what is your total sales tax amount for all three items? *
Add up all items to get the total spent.
Multiply that number by .075 to get the sales tax.
Add the sales tax to the total spent that you found in step 1.
To calculate the total sales tax amount for all three items, you would first need to calculate the sales tax for each item separately.
To calculate the sales tax for an item, you multiply the price of the item by the sales tax rate (in decimal form):
Sales tax for the shirt = $23.90 * 0.075 = $1.7925
Sales tax for the pants = $34.50 * 0.075 = $2.5875
Sales tax for the socks = $3.65 * 0.075 = $0.27375
Now, you can add up the sales tax amounts for each item to find the total sales tax amount:
Total sales tax amount = $1.7925 + $2.5875 + $0.27375 = $4.65375
Therefore, the total sales tax amount for all three items is $4.65375.
