Answer:
Explanation below.
Step-by-step explanation:
Let's say for example you have 100 dollar or euros, or whatever you work with in your country. 30% of 100 equals 30.
If they ask you for example 30% of 250 dollar/euro, it is 250/100 * 30, which equals 75.
If they say there are sales that go up to 30%, all you do is as follows;
1) You calculate how much money 30% is. [Look above]
2) You distract the 30% FROM the original price.
Example; A shirt costs 300 dollar/euro, but there's a sale of 30% on it.
30% of 300 = 100
300-100 = 200
The shirt costs 200 dollar/euro.
