julia wants to purchase a pair of headphones that are on sale for $42.79. the sales tax rate in her county is 6%. how much will julia pay in all for the headphones after sales tax is included? round to the nearest cent if necessary.
Answer
Explanation:
Step1: Calculate sales tax amount
The sales tax is 6% of the price of the headphones. So we find 6% of $42.79. 6% can be written as 0.06. The formula for the sales - tax amount $t$ is $t = 0.06\times42.79$. $t=0.06\times42.79 = 2.5674$
Step2: Calculate total amount paid
The total amount $A$ Julia will pay is the sum of the price of the headphones and the sales - tax amount. So $A=42.79 + t$. $A = 42.79+2.5674=45.3574$ Rounding to the nearest cent, $A\approx45.36$
Answer:
$45.36$
