Answer:
$548.03
Explanation:
To find the total cost of the TV with sales tax included, we need to add the sales tax to the listed price of the TV. The sales tax rate is 7.25%, which means that for every $100 of the listed price, we need to add $7.25 in tax.
First, we can find the amount of tax to be added by multiplying the listed price by the tax rate as a decimal:
tax = listed price x tax rate
tax = $510.98 x 0.0725
tax = $37.05
Next, we can find the total cost of the TV with sales tax included by adding the listed price and the tax:
total cost = listed price + tax
total cost = $510.98 + $37.05
total cost = $548.03
Therefore, the total cost of the TV with sales tax included is $548.03 when rounded to the nearest cent.
