If a store sells a batch of clothes at 150 yuan each, it can make a profit of 25%. The cost price of this kind of clothes is calculated. Suppose the cost price of this kind of clothes is x yuan, then the equation () A. x=150×25%B. 25%×x=150C. 150−xx=25%D. 150-x=25%

Suppose the cost price of this kind of clothing is x yuan, then according to the profit = selling price cost price, we can get the equation: 150-x = 25% X; that is 150 − XX = 25%, so we choose C

1. Mom spends 440 yuan for each suit of clothes. The coat is 5 / 6 of the trousers. How much is a coat and how much is a pair of trousers? (use the equation)
2. As shown in the figure, for a square with 6cm long edges, dig out the largest cone from the bottom of the square. What is the remaining volume in cubic centimeter?
3. Use a 36 meter long fence to surround a rectangular vegetable field. The ratio of length to width is 5:4
(1) What is the area of the land|
(2) If a rectangular vegetable plot is drawn at a scale of 1:200, how many square meters is the area of the plot?

1. If the price of trousers is x, then (5 / 6) x + x = 440, that is, (5 / 6 + 1) x = 440, x = 240, that is, the price of trousers is 240, and the price of coat is 200;
2.6³-(1/3)x3.14x(6/2)²x6=159.48
3. (1) if the length is 5x, then the width is 4x; if 2x (5x + 4x) = 36, and if x = 2, then the length is 10 and the width is 8, so the interview area of this land is 10x8 = 80 square meters;
(2) Area of square graph = (10 / 200) x (8 / 200) = 0.002 square meter
