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

Step-by-step 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:

`(32)/(100)=(x)/(90)`

Step 3

Finally, solve for x

`\begin{gathered} (32)/(100)=(x)/(90) \\ (32\cdot90)/(100)=x \\ x=(2880)/(100) \\ x=28.8 \end{gathered}`

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

I hope this helps you.
