1.
20% of $129 because 129-25.8=103.2

2.
25% of$99 is 74.25 and 25% of $129 is 96.75

3.
you can use math to figure out the amount of a discount

the $99 is the best deal because when you multiply 129 by 20 you get 2580 and then you divide 2580 by 100 and get 25.8 and then you would subtract 129 by 25.8 and get 103.2 so $99 is the better deal

1. The $99 dollar deal is better because the 20% off of $129 because once you put the discount on the $129, it is $103.20, which is still more.

2. With 25% off both of the deals, the $99 deal is still better.
With deal:
$99- $74.28
$129- $96.75

3. Math helps you because you will need to figure out a discount or a tax when you go shopping.

-$99 is a better deal. The Black Friday deal with a 20% discount off of $129 is $103.2. So option one is clearly a better deal.

$129 is the better deal because when you multiply 129 by 25 you get 3325 but you divide by 100 and get 32.25 but then you have to take 129 and subtract that by 32.25 and get 96.75 so 129 is the better deal.

it is the $129 dollar one because if you do 129 multiply 25 then divide 100

Math helps you when you shop because if you have coupons then you could get discounts and when you shop you use tax so you would have to figure out all the total prices.
