IgorC [24]

Answer:

The cost store owner pay for the pair of jeans is <u>$42</u>.

Step-by-step explanation:

Given:

A store owner uses a selling price of 125% of the cost of an item.

If a pair of jeans has a sales price of $52.50.

Now, to find the cost price of the store owner pay for the pair of jeans.

Let the cost price of jeans be x.

Sell price of jeans = \$52.50.

Now, to get the cost price of store owner pay for the pair of jeans:

<em>As given the</em><em> </em><em>store owner uses a selling price of 125% of the cost of an item.</em>

According to question:

125\%\ of\ x=52.50

\frac{125}{100} \times x=52.50

1.25x=52.50

<em>Dividing both sides by 1.25 we get:</em>

x=42.

<em>The cost price of jeans = $42.</em>

Therefore, the cost store owner pay for the pair of jeans is $42.
