Selling price = cost+profit

Price = cost ×( 1+ profit rate)

Profit = selling price-cost

Profit = cost × profit rate

Profit rate = profit/cost

Profit rate = (selling price/cost-1) × 100%

Discount = selling price ÷ pricing × 100% (discount < 1)

Example: A shopping mall will increase the cost price of a sports shoe by 40%, then mark it and sell it at a 20% discount. In this way, each pair can still make a profit of 2 1 yuan. What is the cost price of this badminton suit?

Analysis: Let the cost be X yuan, starting from the cost: (1+40%)x is the marked price. Another 20% discount: (1+40%)x *80% is the selling price. Minus the profit of 2 1 yuan: (1+40%)x *80%-2 1, which is the cost price again. So: (1+40%) x * 80%-21= X. Take a line chart and the equation will be listed.
