Final answer:
To find the sales tax, multiply the total cost by the sales tax rate as a decimal.
Step-by-step explanation:
To find the sales tax for the items, first, find the total cost of the groceries and shirts. In this case, the total cost is $103.40.
Next, calculate the sales tax by multiplying the total cost by the sales tax rate, which is 8%. Convert the percentage to a decimal by dividing it by 100 (i.e., 8/100 = 0.08). Multiply the total cost by 0.08 to find the sales tax in dollars and cents.
Finally, round the sales tax to the nearest cent. The sales tax for the items is $8.27.
