Final answer:
To find the percentage of the subtotal represented by the total, use the formula: Percentage = (Total / Subtotal) * 100. Given the total after-tax, calculate the percentage by solving the equation with the subtotal and tax. Therefore, the correct answer is not listed in the given options, as the percentage is approximately 104.9%.
Step-by-step explanation:
To find the percentage of the subtotal represented by the total, you can use the formula:
Percentage = (Total / Subtotal) * 100
Given that the total amount after tax is $56.42, we need to find the percentage of the subtotal.
We don't have the exact value of the subtotal, but we can still calculate the percentage using the information provided.
Let's consider the subtotal to be 'x'.
We know that (x + 0.05x) = $56.42, where 0.05x represents the tax amount.
Combining like terms, we get 1.05x = $56.42.
Dividing both sides of the equation by 1.05, we find that x ≈ $53.78.
Now we can substitute this value into the percentage formula:
Percentage = ($56.42 / $53.78) * 100 ≈ 104.9%
Therefore, the correct answer is not listed in the given options. The percentage of the subtotal represented by the total is approximately 104.9%.
