Answer:
Below
Step-by-step explanation:
First item)
The original price of the video games is 80$ wich is 100%
This item has a 20% discount.
Let x be the value of the dicount in dollars.
● 80 => 100
● x => 20
● x =(80×20)/100 = 16$
So the amount of the discount is 16$.
● 80-16 = 64 $
So the amount that was paid is 64$

Second item):
The price that was paid is 11.2$out of 14$ initially.
Let x be the percentage of 11.2
● 14$ => 100%
● 11.2$ => x
● x = (11.2×100)/14 = 80%
● 100-80 = 20%
So the percentage of discount was 20%

Third item):
The laptop was boughr for 750$ out of 1000$ initially
No need to do calculations here.
Notice that: 750/1000 = 3/4 = 0.75 = 75%
● 1000-750 = 250
So 250 is the amount discounted wich is 25% of 1000$
