This month's oil import cost is 5% lower than that of last month due to the fact that the oil import cost of a certain country is 5% lower than that of last month Increase by 14%, find the growth rate of this month's oil price relative to that of last month? Write a linear equation with one yuan. Then give me the method,

Suppose the unit price of last month is a, the import volume is x, the unit price of this month is B, and the import volume is (1-5%) X
The total import fee of last month is RMB
This month's import fee is B (1-5%) X
Then [b (1-5%) x-ax] / AX = 14%
The solution is B / a = 1.2
The growth rate is: (B-A) / a = B / A-1 = 0.2 = 20%
If the answer is right, you can ask me if you don't know

The oil import volume of an oil importing country this month is 5% less than that of last month
The oil import volume of an oil importing country this month is 5% lower than that of last month. Due to the rise of international oil price, the cost of oil import this month is 14% higher than that of last month
?

About 22.09%

A country's import of oil is 5% lower than that of last month. Due to the rise of oil price, this month's oil price is 14% higher than that of last month

It's a little strange
