Lin’s father is paying for a $20 meal. He has a 15%-off coupon for the meal. After the discount, a 7% sales tax is applied.
What does Lin’s father pay for the meal? Explain or show your reasoning.
100 - 15 = 85
so
cost before tax = 0.85 * 20 = 17
then 17 * 1.07 = $18.19
Can you tell how to find it if the discount taxes is 4%
So what is the answe
What is it?
To find out what Lin's father pays for the meal, we need to follow these steps:
Step 1: Subtract the discount from the original price.
Step 2: Calculate the amount of tax on the discounted price.
Step 3: Add the tax to the discounted price to get the final amount paid.
Step 1: Subtract the discount from the original price.
The coupon offers a 15% discount on the $20 meal. To find out the discounted price, we need to calculate 15% of $20 and subtract it from $20.
15% of $20 = (15/100) * $20 = $3
Discounted price = $20 - $3 = $17
Step 2: Calculate the amount of tax on the discounted price.
A 7% sales tax is applied to the discounted price of $17. To find out the tax amount, we need to calculate 7% of $17.
7% of $17 = (7/100) * $17 = $1.19 (rounded to two decimal places)
Step 3: Add the tax to the discounted price to get the final amount paid.
The final amount paid is the discounted price plus the tax.
Final amount paid = $17 + $1.19 = $18.19
Therefore, Lin's father pays $18.19 for the meal after applying the 15% discount and 7% sales tax.
