question 12\na customer of a department store wants to buy $85.17 worth of goods, before tax. if there is a sales - tax of 4.5%, how much will the customer pay in sales tax, alone? round appropriately and give your answer with no labels or units of any kind.

Answer

Explanation:

Step1: Identify the formula for sales - tax calculation

The formula for calculating the sales - tax amount is $Sales\ tax\ amount=Purchase\ amount\times Sales\ tax\ rate$.

Step2: Substitute the given values into the formula

The purchase amount is $85.17$ and the sales - tax rate is $4.5%$ or $0.045$ in decimal form. So, $Sales\ tax\ amount = 85.17\times0.045$.

Step3: Perform the multiplication

$85.17\times0.045 = 3.83265$.

Step4: Round the result

Rounding $3.83265$ to two decimal places gives $3.83$.

Answer:

$3.83$
