Question

A store buy jeans from the manufacturer for $30 each and sells them at a 50% increase in price. At the end of the season, they put it on sale for 50% off. Is the sale price $30? Pls explain

Answer 1

Original price = $30
Increase in 50% = 50% of $30 = 0.5 x 30 = $15
Price = 30 + 15 = $45

50% off 
50% of $45 = 0.5 x 45 = $22.50
Price = 45 - 22.50 = $22.50

No, the sales price is not $30
