Answer:
The single discount that is the same as three successive discounts of 20% is 48.8%.
Explanation:
In order to find the answer, you can calculate the three successive discounts of 20% from 100,which would be:
100*20%=20
100-20=80
80*20%=16
80-16=64
64*20%=12.8
64-12.8=51.2
According to this, the amount after successive discounts of 20% is 51.2 and you can subtract this from 100 and that amount would indicate the single discount that is the same as three successive discounts of 20%:
100-51.2=48.8%
