Question

The original price of a pair of jeans at a clothing store was $32.00. Over the weekend, the store owner marked up all the clothing by 10%. What was the new price of the jeans?

Answer 1

the new price of the jeans is $28.8

Explanation

Step 1

Let

original price= 100 %

new price(%)=original price(%)-discount(%)

then

new price(%)=100-10

new price=90% of the original price

Step 2

we can use a rule of three to find the 90%

Let

x represents the value in dollar for the 90%

if

$32\Rightarrow100\text{ percent}$

then

$x\Rightarrow90\text{ percent}$

As the proportion is the same:

$\frac{32}{100}=\frac{x}{90}$

Step 3

Finally, solve for x

$\begin{gathered} \frac{32}{100}=\frac{x}{90} \\ \frac{32\cdot90}{100}=x \\ x=\frac{2880}{100} \\ x=28.8 \end{gathered}$

Hence, the new price of the jeans is $28.8.

I hope this helps you.
