Question

$4.30 makeup; 40% discount; 6% tax

Answer 1

I'll walk you through the steps,  
first you find the discount--- 4.3 * .4 = 1.72
Subtract discount from original price---4.30 - 1.72 = 2.58
2.58 is now the sale price after the discount.
Now to add tax we must multiply---00.6 * 2.58 = .1548
Add sales to tax price---2.58 + 0.15 = 2.73
So the sale price including tax and the discount will be $2.78
Hope this isn't too confusing and hope it helps<span />
