pls help me i can't figure this out and i have to finish it

Answer:
Because 20% of $10 will not be the same as 20% of a larger number
Step-by-step explanation:
120% of 10= 1.2(10)=$12
So we added $2 on the mark up.
Marking 20% off of $12 means the price will be 80% of 12= .8(12)= $9.60
This was a reduction of $2.40 which is 20% of $12
Answer:
Step-by-step explanation:
20% of 10 is $2
Marked up: 10+2 = $12
Marked down: 20% of 12 is 2.40 = 12-2.40 = $ 9.60
20% of 10 is not the same as 20% of 12.
