320,000÷100=3200
1/100=3200
×15=48,000
therefore 15/100=48,000
D≈2π(6371-1737.5)
d≈9267π

Answer:
12 > x+5 (?) 52
Step-by-step explanation:
100% of the price = $400
x % of the price = $320
we need to find x
using a proportion
100 : 400 = x : 320
100 * 320 = 400 * x
32000 = 400x
x = 32000 / 400
x = 80
That means the new price is 80% of the previous price.
100% - 80% = 20%
and based on this we can make a conclusion that the discount was 20%
I hope it is clear to you, feel free to ask anything about it :)
