Li Ming used the summer vacation to work in a bicycle factory

Whoever came up with this question asked him to answer it himself. The daily remuneration remains the same, which means that in addition to the car and 200 yuan, the daily remuneration is still calculated? Are the two the same for the new bike? Neither side did what was agreed, and this is how education now teaches our future generations what integrity is?

Because there is already a premise, the daily wage remains the same, in the case of different working days, or get two things, indicating that the front and rear ** of the bicycle is not the same, according to the topic can be concluded that the ** of the bicycle is an integer, and the mantissa is 0, (because the salary is minus 200, and the commonly used pricing is the same) According to the previous working hours, it can be deduced that his salary for 49 days of work is approximately, 490,980, 10 yuan per day, 20 yuan, and so on. The daily salary is 10 yuan, 280 yuan for 28 days, and only 80 yuan for 200 yuan, which is unreasonable. The daily salary is 20 yuan, 560 yuan for 28 days, minus 200, 360 yuan, according to the nature of the business, it can be concluded that the ** of the bicycle is 360 yuan.

Those with the answer of 250, I have a question, 450 is not divisible by 28, how did you come up with that?

The question asked by this person is level, Li Ming's salary is based on the new bicycle no matter what. But the bikes, although new, are in the middle and middle range. Not certain**.

The cash is two hundred. However, Li Ming's working hours are different, and it is impossible to pay the same for different working hours. There is no satisfactory answer to this question

The question is naïve, the cheapest bicycle does not exceed a hundred, and the expensive can reach tens of millions.

Generally speaking, as you said, the value is probably between 1-300.

How did today's students degenerate to the point where they couldn't even ask questions?!

You're sick, this front x = back x, you go and count.

Can you explain the problem clearly? Hehe.

The value of the bicycle is x yuan, x + 200

49=x+20

28,49x+980=28x+5600,21x=4620,x=220,A: The value of a bicycle is 220 yuan

Set the bicycle value to be $x.

Then: 4 7=(x+20) (x+200).

Calculate: x=220

Set up a clever quick grinding week, the reward of Changzao is x yuan.

7x-4x=200-20

x=60, so the pay for 4 weeks is 60*4=240 yuan.

Except for the 20 yuan, the rest is the value of the bicycle 220 yuan.

Set up a bicycle x yuan, Xiaohua earns y yuan a week.

x+300=7y

x+30 =4y

x=330 so the bike is worth 330

300-30 = 270 yuan is the money he gets for three weeks, then one week is 90 yuan, so four weeks is 360 yuan, and the ** subtract 30 yuan to get the bicycle is 330 yuan. That's it.

Suppose a new bicycle is worth $x.

x+200）/49=(x+20)/28

Simplification yields 28x+5600=49x+980

Solution x = 220 yuan.

A: This new bike is 220 yuan.
