A hammer that normally sells for $24 is on sale for $12. What percentage is the discount?

A) 288%

B) 50%

C) 2%

D) 0.50%

Answer: B) 50%

Work Shown:

P = original price = 24

Q = discount price = 12

P-Q = amount saved = 24-12 = 12

Divide this amount over the original

(P-Q) / P = 12/24 = 0.50 = 50%

So you save half (save $12) and pay the other half (pay $12)

B) half of it 50 and 50!
