In order to promote sales, a shopping mall reduced the price of a commodity by 18%. Later, it was found that it lost money to sell at this price, so it increased by 8%. After two price adjustments, the price was 177.12 yuan, How much is the original price?
Suppose the original price of the commodity is x yuan
According to the meaning of the question, there are (1-18%) (1 + 8%) x = 177.12
0.82×1.08X=177.12
X=200
A: the original price of the product is 200 yuan
The cost of computers is constantly decreasing. If the price of computers is reduced by 13 every three years, the price of computers with 8100 yuan now will be reduced to ()
A. 2400 yuan B. 900 yuan C. 300 yuan D. 3600 yuan
The price of computer in 9 years is 8100 × (1 − 13) 93 = 8100 × (23) 3 = 2400
The cost of computers is constantly decreasing. If the price of computers is reduced by 13 every three years, the price of computers with 8100 yuan now will be reduced to ()
A. 2400 yuan B. 900 yuan C. 300 yuan D. 3600 yuan
The price of computer in 9 years is 8100 × (1 − 13) 93 = 8100 × (23) 3 = 2400
The cost of computers is constantly decreasing. If the price of computers is reduced by 13 every five years, and the current price of computers is 8100 yuan, the price can be reduced to 10 yuan in 15 years______ (yuan)
From the meaning of the question, it can be concluded that the price after every five years is an equal ratio sequence with the common ratio of (1-13) and the first item of 8100, so the price of the computer after 15 years is: 8100 × (1-13) 3 = 2400 (yuan). So the answer is: 2400
The cost of computers is constantly decreasing. If the price of computers is reduced by 13 every three years, the current price of 8100 yuan computers will be 9 years later______ Yuan
∵ the price of computer is reduced by 13 every three years, the current price is 8100 yuan ∵ the relationship between the price of computer and the year n is y = 8100 × (23) N3 ∵ the price after 9 years is y = 8100 × 827 = 2400 yuan, so the answer is: 2400
The cost of computers is constantly decreasing. If the price of computers is reduced by 1 / 3 every three years, the price of 2400 yuan computers now is 3 years ago
Set X Yuan three years ago
X-1/3X=2400
X = 3600 yuan
