The total cost of skateboard after tax is removed = $87.53
Explanation:Initial cost of scateboard = $79.57
Discount = 12%
Discounted price = Initial cost of scateboard × 12%
= 79.57 × 0.12
Discounted price = 9.5484 = $9.55
Note: Discount is subtracted while sales tax is added to the cost of item
The amount left after discount is removed before tax= Initial cost of scateboard - Discounted price
The amount left after discount is removed = $79.57 - $9.55
The amount left after discount is removed = $70.02
Sales tax = 25%
Amount of sales tax = The amount left after discount is removed × 25%
= $70.02 × 0.25 = 17.505
Amount of sales tax = $17.51
The total cost of skateboard after tax is removed = The amount left after discount is removed + Amount of sales tax
The total cost of skateboard after tax is removed = $70.02 + $17.51
The total cost of skateboard after tax is removed = $87.53
