A retailer adds 30% to the cost price of all the goods that he sells. He offers a trade discount of 10% to some customers. If a customer receives the trade discount and pays K88.92 for an article:

1. What was the cost price to the retailer of the article? Show work.

Let the cost price of the article be x.

The retailer adds 30% to the cost price, so the selling price without discount is:
Selling price = x + 0.3x = 1.3x

The customer receives a 10% trade discount, so they pay 90% of the selling price:
0.9(1.3x) = K88.92

1.17x = K88.92
x = K88.92 / 1.17
x = K76

Therefore, the cost price to the retailer of the article was K76.

Sure, here's a more detailed breakdown of the calculations:

1. Let x be the cost price of the article to the retailer.
2. The retailer adds 30% to the cost price, so the selling price without discount is 1.3x.
3. The customer receives a 10% trade discount, so they pay 90% of the selling price.
4. Therefore, the customer pays 0.9 * 1.3x = 1.17x for the article.
5. We are given that the customer pays K88.92 for the article, so we can set up the equation:
1.17x = K88.92
6. To find the cost price to the retailer, we solve for x:
x = K88.92 / 1.17
x = K76

Therefore, the cost price to the retailer of the article was K76.

Write in equation form w

Sure, here's how the calculations can be expressed in equation form:

Let x = cost price of the article to the retailer.
Selling price without discount = 1.3x
Customer pays 90% of the selling price = 0.9 * 1.3x = 1.17x
Given that the customer pays K88.92 for the article, we set up the equation:
1.17x = K88.92

Solving for x:
x = K88.92 / 1.17
x = K76

Therefore, the cost price to the retailer of the article was K76.

Let the cost price to the retailer be x.

The retailer adds 30% to the cost price, so the selling price without discount is:
1.3 * x

The customer receives a 10% trade discount, so they pay 90% of the selling price:
0.9 * (1.3 * x) = 1.17 * x

Given that the customer pays K88.92 for the article:
1.17 * x = K88.92

Solving for x:
x = K88.92 / 1.17
x = K76

Therefore, the cost price to the retailer of the article was K76.
