### Solution:

Concept- The price at which a seller buys a product is called the cost of the product, and the price at which a seller sells a product to a consumer is called the sale of the product to the seller. If the selling price of a product is higher than the cost price of the product, the price difference can be called the profit or profit of the product, and at the same time the selling price is lower than the cost price of the product. Price differences are called product losses. Product win or loss rates are always calculated based on the cost of the product.Sales tax is the amount that a customer pays to the government at the time of purchase and is always added to the selling price. This question shows the cost, and the customer calculated the sales tax by making a profit of 6% at the dining table using the profit margin formula to find the selling price of the table, and then adding 5%. say. Selling price to find the total price paid by the customer. Dining table cost The customer made a profit of 6%, so use the rate of return formula to find the selling price.
