1.
40/50 x 100
4000/50 =
= 80%
2.
If it falls to 25%, the new price will be $ 9600
100% - 25% = 75% of the cost of the old
If 75% = 9600
100% = (100 x 9600) / 75
960000/75 =
= $ 12,800
3.
Find 20% 0F $ 70
= 20% / 100% X 70
= 1 / 5 X 70
= $ 14
The reduced price is
$ 70 - $ 14 = $ 56
2. Be the first prize x.
x - .25 x = 9600
.75 X = 9600
x = $ 12,800
3. If the discount of 20%, 80% of the original price paid.
.8 (70) = $ 56
Or 70 .2 (70) = 70 - 14 = $ 56
1. (40/50) * 100% = 80%
2. 9600 * 100 / (100-25) = $ 12,800
3. 70 * (100-20) / 100 = $ 56
