Final answer:
Jamie's total cost for a $25 pair of jeans with an 8.5% sales tax would be $27.13 after calculating and adding the rounded tax amount to the original purchase price.
Step-by-step explanation:
Calculating Total Cost After Sales Tax
Jamie bought a pair of jeans for $25. The total cost after including the county tax rate of 8.5% needs to be calculated. To find the sales tax, the tax rate should be converted to a decimal by dividing it by 100. Therefore, 8.5% becomes 0.085. Next, multiply the price of the jeans by this decimal to find the amount of tax.
Calculate sales tax: $25 × 0.085 = $2.125.
Since the tax is typically rounded to the nearest cent, we round $2.125 to $2.13. After finding the sales tax, it needs to be added to the original price to obtain the total cost.
Total cost after tax = Original price + Sales tax
Total cost after tax = $25 + $2.13 = $27.13.
Therefore, Jamie's total cost after taxes for the pair of jeans is $27.13.
