A pair of jeans are priced at $129.99 there is a discount of 20% and sales tax of 8% what is the final cost

Calculate discounted price:
Discounted price = Full price * (100% - discount percent)
Discounted price = 129.99 * (100% - 20%)
Discounted price = 129.99 * 80%

Since 80% = 0.8, we have:
Discounted price = 129.99 * 0.8
Discounted price = 103.99

Calculate after tax cost:
Tax Rate = Tax percent/100
Tax Rate = 8/100
Tax Rate = 0.08

After Tax cost = Discounted price * (1 + Tax rate)
After Tax cost = 103.99 * (1 + 0.08)
After Tax cost = 103.99 * 1.08
After Tax cost = 112.31
