Question

A family buys groceries for $149.98,

including $10.07 in taxes. The bill includes $26.95 worth of items that
are not taxable. Find the sales tax rate. Round your answer to the nearest
tenth of a percent.

Answer 1

To find the sales tax rate, calculate the taxable amount and divide the amount of taxes paid by the taxable amount. Rounded to the nearest tenth of a percent, the sales tax rate is 8.2%.

Step-by-step explanation:

To find the sales tax rate, we first need to calculate the total taxable amount. Substract the value of non-taxable items from the total bill:

Taxable amount = Total bill - Value of non-taxable items

Taxable amount = $149.98 - $26.95 = $123.03

Next, we divide the amount of taxes paid by the taxable amount:

Sales tax rate = Taxes paid / Taxable amount

Sales tax rate = $10.07 / $123.03

Sales tax rate = 0.0819 (rounded to four decimal places)

Rounded to the nearest tenth of a percent, the sales tax rate is 8.2%.
