Answer:
Mary was charged a 6% tax
Explanation:
To find the percentage tax Mary was charged, we need to determine the amount of tax she paid and then calculate that as a percentage of the original purchase price.
We know that the total bill after tax was $25.44, and the purchase price before tax was $24, so the tax paid must be:
$25.44 - $24 = $1.44
To find the percentage tax charged, we need to divide the tax paid by the original purchase price, then multiply by 100 to express the answer as a percentage:
($1.44 / $24) x 100% ≈ 6%
Therefore, Mary was charged a 6% tax.
