Answer:
Total price: $74.10
Step-by-step explanation:
Given the $57 amount, and the additional 30% tax:
Step 1: Conversion of 30% to Decimal Form
First, we must determine the nominal amount of 30% tax. In order to do so, simply convert 30% to its decimal form:
Conversion methods from percentage to decimal form:
Method 1: move the decimal point two places to the left, which results in 0.30.
Method 2: Divide 30 by 100: [tex]\displaystyle\mathsf{\frac{30}{100}\:=\:0.30}[/tex]
Step 2: Determine the nominal equivalence of 0.30 (tax)
Multiply $57 by 0.30 to find how much is the dollar value of the 30% tax.
$57 × 0.30 = $17.10
Step 3: Find the total price
Add $57 and $17.10 to determine the total price:
$57 + $17.10 = $74.10
Therefore, the total price is $74.10.
