Just use this equation that I made up for your benefit: C=A*n Where C is the cost of gasoline per month. A is the average cost of your gasoline per day and n is the number of days in the month you are referencing To find A though(the average cost of your gasoline per day), you can use this formula: A=C/n Where A is the average cost of your gasoline per day C is the cost of gasoline per month and n is the number of days in the month you are referencing However, in order to find the average cost of your gasoline per day, a step in the process to finding the cost of your gasoline per month, you already have to know the cost of your gasoline per month(in order to plug this number into the average cost function). Pretty much, to answer your question, you already have to know the answer. *All the information in this answer is correct, and hopefully you can use it to improve your problem solving skills. Or you can save your receipts add he totals and divide by the number of months you have collected. (I know the simple answer always comes last after much thought and research - much like the government!)
Let's say you drive on an average "M" miles per month and you car travels on average "m" miles per gallon and the average price of gasoline is "p" per gallon, then the avaerage cost of gasoline for one month is (M x p)/m
It cost 3.95
david bought 15 gallons of gasoline. his total cost was $13.60. how much was the gasoline per gallon?

On 1975 it cost about 27 cents

Intensive because the price of gasoline is not going to change no matter how much you get.
Gasoline is old after a month. Especially gasoline which contains ethanol. Ethanol looses its octane rating much faster than petroleum.
