To find the purchase price of the stereo, we need to follow these steps:

Step 1: Calculate the selling price after markup.
The markup percentage is 75%.
So, the selling price after markup can be calculated by adding the markup percentage to the cost price:
Markup Amount = (Markup Percentage/100) * Cost Price
Markup Amount = (75/100) * $27

Step 2: Calculate the selling price before discount.
Selling price before discount = Cost Price + Markup Amount

Step 3: Calculate the sale price after discount.
The stereo was on sale at 40% off the selling price before the discount.
Sale Price = Selling Price before discount - (Discount percentage/100) * Selling Price before discount

Now, let's calculate the purchase price of the stereo.

Step 1:
Markup Amount = (75/100) * $27
Markup Amount = $20.25

Step 2:
Selling price before discount = $27 + $20.25
Selling price before discount = $47.25

Step 3:
Sale Price = $47.25 - (40/100) * $47.25
Sale Price = $47.25 - $18.90
Sale Price = $28.35

Therefore, the purchase price of the stereo was $28.35.

To find the purchase price of the stereo, we need to follow a sequence of calculations.

First, let's calculate the selling price after the markup. The markup amount can be calculated by multiplying the cost by the markup percentage:

Markup amount = Cost × Markup percentage/100
= $27 × 75/100
= $20.25

Next, we need to calculate the marked up price, which is the cost plus the markup amount:

Marked up price = Cost + Markup amount
= $27 + $20.25
= $47.25

Now, we need to calculate the sale price after the customer received a 40% discount. The discount amount can be calculated by multiplying the marked up price by the discount percentage:

Discount amount = Marked up price × Discount percentage/100
= $47.25 × 40/100
= $18.90

Finally, we can calculate the purchase price by subtracting the discount amount from the marked up price:

Purchase price = Marked up price - Discount amount
= $47.25 - $18.90
= $28.35

Therefore, the purchase price of the stereo was $28.35.
