Luis wanted to buy a skateboard that usually sells for $79.99. all merchandise is discounted by 12%. what is the total cost of the skateboard if luis has to pay sales tax of 6.75%

Here are the steps, then I'll go through the steps.

1. Find the amount of the discount by finding what 12% of $79.99 is.
2. Subtract the discount from $79.99. This the discounted price.
3. Find how much 6.75% of the discounted price is. This is the amount of tax.
4. Add the amount of tax to the discounted price.

1. 12% of $79.99 = 12% * $79.99 = 0.12 * $79.99 = $9.60
The amount of the discount is $9.60.

2. $79.99 - $9.60 = $70.39
The discounted price is $70.39

3. 6.75% of $70.39 = 6.75% * $70.39 = 0.0675 * $70.39 = $4.75
The tax amount is $4.75.

4 $70.39 + $4.75 = $75.14

The total cost is $75.14
