A blouse of 100 yuan is more expensive than the price of a pair of pants of 40 yuan 20 yuan, how muc

This is a problem for the application of simple equations, and the key to the equation problem is to find the equivalence relationship in the problem! You can set pants**, pants** multiply 40% plus 20 equals top**! The specific process is as follows:

Hope, thank you!

Let the ** of this pants be x, then we can get: 40%x+20=100

x=200

So the price of the pants is 200 yuan.

Untie a pair of pants for $ x.

40%x+20=100

x=80 x=200 A: 200 yuan for a pair of pants.

Untie a pair of pants for $ x.

40％x＋20＝100

40％x＝100-20

x＝80÷40%

x 200 yuan.

A shirt is 100 yuan, and the ** of a pair of pants is x yuan, then (1+40%)x=100, x=100 yuan.

Hello friends, let's say the ** of a pair of pants is $x.

Then, x multiply by 40% + 20 = 100 yuan.

Thus x=200 yuan.

From the known conditions, it can be seen that if you solve the equation, you will treat a pair of pants as an x-element. 40% x plus 20 equals 100. You can solve this equation and figure out how much a pair of pants cost?

Solution: Let a pair of pants be x-yuan, then the column equation is as follows, and the solution equation obtains: x 80

Answer: The ** of a pair of pants is 80 yuan.

Summary. The correct quantity relationship is the ** 2 + 20 = ** of the top, so the ** of the pants is (150 20) 2 = 130 2 = 65 (yuan).

A blouse costs $120 more than 2 times the price of a pair of pants, $20 more, how much is a pair of pants.

The correct quantity relationship is the **grinding of the pants 2+20=the ** of the top**, so the price of the pants is (150 20) 2=130 2=65 (yuan).

Can you add, I don't quite understand it.

150-20) 2=65 The correct quantitative relationship is (** of the top - more **) Multiple = ** of the pants.

Pants can be calculated for 222 yuan. Assuming that the jacket is x yuan, and the other is 1 percent minus 20x, then we can get that 1.8x is equal to 500, and x is about 278. So the pants are 500 minus 278 equals 222 yuan.

Summary. Dear, according to your questions. A pair of pants costs 40 yuan, a blouse is 15 yuan more expensive than a pair of pants, and a total of 95 yuan to buy this set of clothes. <>

A pair of pants costs 40 yuan, a top is more expensive than a pair of pants, 15 yuan, how much does it cost to buy this set of clothes?

Dear, according to your questions. A pair of pants costs 40 yuan, a blouse is 15 yuan more expensive than a pair of pants, and a total of 95 yuan to buy this set of clothes. <>

Dear, we can calculate it this way, the ** of a pair of pants is 40 yuan, if a top is 15 yuan more expensive than pants, then the ** of the clothes is 55 yuan. So the ** of pants and clothes is 40 + 55 95 yuan. <>
