The tank of John's car is full: it contains 47 liters of gasoline. After a journey of 275 km, there are 14 liters left. What is the fuel consumption of this car per 100 km?
The car consumed 47 liters - 14 liters = <<47-14=33>>33 liters of gasoline for 275 km.
Let x be the fuel consumption per 100 km. We can write the proportion: 33/275 = x/100
The cross product gives: 275 x = 33 * 100
So the car consumes x = 3300/275 = <<3300/275=12>>12 liters per 100 km.

Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
You are solving math problems. Here are some examples of how to solve the task:

Today is my birthday and I'm three times older than I was six years ago. What is my age?We know that my age divided by three is equal to my age minus six therefore X/3 = X-6 where X = My age
This means that X = 3X - 18 because we can multiply both sides by 3
This also means that -2X=-18 because we can subtract 3X from the right side.
Therefore X = 9 because - 18/-2 = <<-18/-2=9>>9

Mary went to the store to buy fruit. Apples cost $1, oranges cost $2, and bananas cost $3. For every 5 fruits that customers buy, the store offers a $1 discount. Mary buys 5 apples, 3 oranges, and 2 bananas. How much will she pay?For 5 apples, Mary will pay 5*1= <<5*1=5>>5 dollars.
For 3 oranges, she will pay 3*2= <<3*2=6>>6 dollars.
For 2 bananas, she will pay 2*3 = <<2*3=6>>6 dollars.
She bought 5+3+2=<<5+3+2=10>>10 fruits
For 10 fruits, Mary gets a discount of 10/5 = <<10/5=2>>2 dollars.
In total, the bill is 5 + 6 + 6 = <<5+6+6=17>>17 dollars.
Subtracting the discount offered by the stores, Mary will pay 17 - 2 = <<17-2=15>>15 dollars.

Now, solve this next question in the style of the above examples:

The tank of John's car is full: it contains 47 liters of gasoline. After a journey of 275 km, there are 14 liters left. What is the fuel consumption of this car per 100 km?

### Response:
The car consumed 47 liters - 14 liters = <<47-14=33>>33 liters of gasoline for 275 km.
Let x be the fuel consumption per 100 km. We can write the proportion: 33/275 = x/100
The cross product gives: 275 x = 33 * 100
So the car consumes x = 3300/275 = <<3300/275=12>>12 liters per 100 km.
