Final answer:
To calculate the total cost of a $600 suit with a 20% discount and an additional 5% sales tax, you first find the discounted price, then add the sales tax to that amount, resulting in a final total of $504.
Step-by-step explanation:
To find the total price you have to pay for a suit that normally costs $600 and is currently on sale with 20% off, and then will have a 5% sales tax applied to the reduced price, follow these steps:
Calculate the discount by converting the percentage to a decimal (20% is 0.20) and multiplying it by the original price:
$600 × 0.20 = $120.
Subtract the discount from the original price to find the sale price:
$600 - $120 = $480.
Calculate the sales tax by converting the tax rate to a decimal (5% is 0.05) and multiplying it by the sale price:
$480 × 0.05 = $24.
Finally, add the sales tax to the sale price to find the total cost:
$480 + $24 = $504.
The total price you have to pay for the suit, with the discount and sales tax included, is $504.
