1A. 12.99*5%=12.99*.05=0.65 this is the sale tax
12.99 + 0.65= 13.64 is the price after tax

1B. 12.99*20%=12.99*0.2=$2.6 is discount
12.99 - discount= 12.99 - 2.6=10.39 is the price after discount was applied
10.39*5%=10.4*0.05=0.52 is the tax
10.39+.52=$10.91 is the price after discount with 5% tax

2A. 329.00*15%= 329.00*0.15=$49.35 this is the discount.
329 - discount = 329 -49.35=$279.65 discounted price

2B. 329*10%=329*0.1=32.9 is how much more the ipad will cost compared to the old price (increase in price). Now add it to the old price: 329 + 32.9=$361.9 is new price

361.9*10%=361.9*0.1=36.19 is a sale tax after change in price
361.9+36.19=$398.09 is the final price
