A pair of jeans priced at $49.95 is on a 20% off sale, which calculates to a discount of $9.99. The calculation involves multiplying the sale price by 20%, resulting in a final price of $39.96 after the discount. The discussion highlights the importance of understanding percentage calculations in retail pricing. It also notes that a 20% discount does not imply the jeans cost 20% of the original price. Accurate calculations are essential for determining sale prices effectively.

20/100=0.20. What is 0.20*49.95? Do you have a calculator? Unusual question for 'Advanced Physics'!
 
that would equal 9.99!
 
20% off doesn't mean it costs 20%
