Luis wants to buy a skateboard that usually sells for $79.99
all merchandise is discounted by 12% = 0.12
Discount amount = sale price * discount percentage
= 79.99 * 0.12 = 9.5988
Selling price after discount = 79.99 - 9.5988 = 70.3912
Now we apply sales tax for the price after discount
sales tax of 6.75 % = 0.0675
Tax amount = price after discount * tax percentage
= 70.3912 * 0.0675= 4.751406
the total cost of the skateboard = Price after discount + tax amount
=70.3912 + 4.751406 = 75.142606
$75.14 is the total cost of the skateboard
The correct answer is:
$75.14
Explanation:
Everything is discounted 12%. This means that Luis will pay 100%-12% = 88% of the original cost.
88% = 88/100 = 0.88; this means 88% of 79.99 is
0.88(79.99) = 70.3912 ≈ $70.39.
Tax is 6.75%. This means he will pay 100% of his discounted price and an extra 6.75% tax; this is 100%+6.75% = 106.75%.
106.75% = 106.75/100 = 1.0675; this means that 106.75% of 70.39 is
1.0675(70.39) = 75.141325 ≈ $75.14.
