A chair normally priced at $75, is marked down to $41.25. What is the percentage decreased for the chair?

Answer:
The answer is B. I think.
Step-by-step explanation:
$75 divided by 10 is 7.5
7.5 = 10%
$41.25 divided by 7.5 or 10% = 5.5
5.5 x 10 = 55%
Sorry if this is not helpful.
Answer: 45%
Step-by-step explanation: 75 - 41.25 = 33.75
75 / 75 = 1 • 100 = 100
33.75 / 75 =0.45 • 100 = 45
