Answer 8

All clothing is 25 percent off. The original price of $28.

25% = 0.25

$28 - (0.25)* $28 = $28 - $7 = $21

The price of the item after discount of 25% , is 21 dollars.

Another way to think of it, You are paying 75% of the cost, or 0.75 of 28
(0.75)*28 = 21 dollars

Answer 9

The sales tax rate is 8 percent and is calculated on the discounted price

8% = 0.08
Need to add on 8% of that 21 dollars at tax.

$21 + 0.08*$21 = $21 + $1.68 = $22.68

The total price after discount and tax is $22.68

If He has 24 dollars, he has enough for the item.
