Understanding the Problem
When purchasing a new LCD television, it's essential to consider the total cost, including tax. In this scenario, the television costs $890, and an 8.1% tax is applied. To determine the total cost, we need to calculate the tax amount and add it to the original price of the television.
Calculating the Tax Amount
The tax amount can be calculated by multiplying the original price of the television by the tax rate. In this case, the tax rate is 8.1%, which can be expressed as a decimal by dividing by 100: 8.1 ÷ 100 = 0.081.
Tax Amount = Original Price × Tax Rate
Tax Amount = $890 × 0.081
Tax Amount = $72.29
Calculating the Total Cost
To find the total cost of the television, we need to add the tax amount to the original price.
Total Cost = Original Price + Tax Amount
Total Cost = $890 + $72.29
Total Cost = $962.29
