Question

Jackie is buying a new blouse, the original price is $24.00 and it is on sale for $18.00, what is the percent of decrease? A 10% B 15% C 20% D 25%

Answer 1

25% (option D)

Explanation:

Old price = $24.00

New price = $18.00

$Percent\text{ of }decrease=\text{ }\frac{new\text{ price - old price}}{\text{old price}}\times100$$\begin{gathered} \text{Percent of decrease =}\frac{18-24}{24}\times100 \\ =\frac{-6}{24}\times100 \end{gathered}$$\begin{gathered} \text{percent of decrease = -}0.25\times100 \\ \text{percent of decrease = -}25\text{percent} \end{gathered}$

Percent of decrease is 25% (option D)
