Question

a laptop has a listed price of $757.98 before tax. if the sales - tax rate is 9.5%, find the total cost of the laptop with sales tax included. round your answer to the nearest cent, as necessary.

Explanation:

Step1: Calculate the sales - tax amount

The sales - tax rate is $9.5\%=0.095$, and the listed price of the laptop is $P = 757.98$. The sales - tax amount $T$ is calculated by multiplying the listed price by the sales - tax rate. So $T=757.98\times0.095$.
$T = 757.98\times0.095=72.0081$.

Step2: Calculate the total cost

The total cost $C$ of the laptop is the sum of the listed price and the sales - tax amount. So $C=757.98 + 72.0081$.
$C=829.9881\approx829.99$.

Answer:

$829.99$
