The average price per gallon of gas again reached $4 on Monday, CNN Business reported.
Gas rose above the $4 per gallon price on March 31, with gas prices rising and falling as the Iran war continues to start and stop.
Before the war, the average price was around $2.98 a gallon. And after the war began, prices rose to a four-year high of $4.56 before falling again.
The price of oil per barrel sits around $82.
