Since when?
Yes the form is -- have/has + past participle. My wages have increased. The price of petrol has increased.
100*10/(100+10)=9.09%
That is totally dependent on the price for the petrol and and the miles per gallon rating on the vehicle.
because the driving age has gone up so there is less people buying petrol. so you have to pay more for it cause there less people paying for it
Average price was about £1.75 per gallon.
The price depends on the petrol supplier, how much they charge for the company who owns the petrol station. It also depends on how much of a profit the companies want to make. Say if sainsburys had a petrol station somewhere, prices 110p per litre, they could be making 10p profit off the petrol suppliers price which could be 100p per litre.
The cost of a liter of petrol in the United States of America in 1983 was $4 per little. The price has however gone up because of the increased demand and the depleted sources.
It depends on the country in which you live. The price varies considerably.
The price of a liter of unleaded petrol varies depending on location and current market conditions. As of September 2021, the average price of a liter of unleaded petrol is around $1-2 USD in the United States.
I don't know who asked that question, but he must be f***ed in the brain
Because the petrol price has gone up?
The changing of petrol price affects the rate of inflation. When petrol price increases, it follows that the cost of production and transportation of most goods also increase.
