A crockery store offered a sale of 15% on their products. If a specific product was already on 10% sale, what is the percent decrease from the original price before any discount to the current price?

a. 5%

b. 10.5%

c. 15%

d. 23.5%

e. 25%

Let $100 = the original price.

After a 10% discount, the new price = $100 - (10% of $100)

= $100 - ($10)

= $90

After a further 15% discount, the new price = $90 - (15% of $90)

= $90 - ($13.50)

= $76.50

What is the percent decrease from the original price before any discount to the current price? The price has decreased from $100 to $76.50

Percent decrease = (100)(change in value)/(original value)

= (100)(100 - 76.50)/100

= (100)(23.5)/100

= 23.5%

Answer: D
