There is a 25% discount on a 50-inch TV that sells for $349. Sales tax is 4%. How much is the total cost after tax?
1.04(0.75 * 349) = $____
Cost = (0.75+0.04) * 349 = $275.71.
I agree with Ms. Sue
price after 25% discount = .75(349)
after sales tax, price = 1.04(.75(349)) = $272.22
0.75 * 349 = $261.75 = Price after discount.
Total cost = 261.75 + 0.04*261.75 = $272.22.
Ms. Sue is correct! Thanks Reiny!
To calculate the total cost after tax, you need to first calculate the discount amount, then subtract that from the original price to find the discounted price. Finally, you add the sales tax to the discounted price to get the total cost after tax.
Step 1: Calculate the discount amount
The TV has a 25% discount, so you need to find 25% of the original price. To do this, multiply the original price by 0.25 (which is the decimal form of 25%) as follows:
Discount amount = $349 * 0.25 = $87.25
Step 2: Find the discounted price
To calculate the discounted price, subtract the discount amount from the original price:
Discounted price = $349 - $87.25 = $261.75
Step 3: Add the sales tax
The sales tax is 4%. To calculate the sales tax amount, multiply the discounted price by 0.04 (which is the decimal form of 4%):
Sales tax amount = $261.75 * 0.04 = $10.47
Step 4: Calculate the total cost after tax
To find the total cost after tax, add the discounted price and the sales tax amount:
Total cost after tax = $261.75 + $10.47 = $272.22
Therefore, the total cost of the 50-inch TV after tax is $272.22.
