    There is a sales tax of $5 on an item that costs $51 before tax. A second item costs $173.40 before tax. What is the sales tax on the second item?

    Calculate the sales tax percent using the first item:
    Sales Tax Decimal = 100% * Sales Tax / Pre-Tax Bill
    Sales Tax Decimal = 100% * 5/51
    Sales Tax Decimal = 0.098

    Calculate the sales tax on the second item:
    Sales Tax = Pre-Tax bill * (1 + Sales Tax)
    Sales Tax = $173.40 (1 + 0.098)
    Sales Taax = $173.40 * 1.098
    Sales Tax = $190.39
