A TV that usually sells for $188.10 is on sale for 30% off. If sales tax on the TV is 7%, what is the price of the TV, including tax?
To find the price of the TV, including tax, we need to follow these steps:
Step 1: Calculate the discount amount.
To find the discount amount, we need to multiply the original price ($172.36) by the discount rate (25%).
Discount amount = $172.36 * 0.25 = $43.09
Step 2: Calculate the sale price.
To find the sale price, we need to subtract the discount amount from the original price.
Sale price = $172.36 - $43.09 = $129.27
Step 3: Calculate the tax amount.
Now, let's calculate the tax amount. We need to multiply the sale price by the tax rate (9%).
Tax amount = $129.27 * 0.09 = $11.63
Step 4: Calculate the final price.
To find the final price, we need to add the sale price and the tax amount.
Final price = $129.27 + $11.63 = $140.90
Therefore, the price of the TV, including tax, is $140.90.
