Welcome to numerid in the current problem we are given that jake buys a t -shirt that is marked at the price $80 and he receives a discount of 10%.
00:20
So how much does he pay for the shirt? now understand if the price of the shirt, if the price was 100, then discount would have been $10, correct? so then how much would be the discounted price? discounted price, dp.
00:46
That would be 100 minus 10, that is $90, correct? so therefore, if you think something that is priced at $100 will get reduced to $90 if there is a 10 % discount.
01:03
Therefore, something that is marked at 1 will get reduced at 90 by 100.
01:10
Correct? this is a 0.
01:13
Then, what will be the price of something that is marked at 80? so, it will be 90 into 80 divided by 100.
01:28
So, the zeros cancel with each other...
