I need help estimating the cost of gasoline for a trip Im planning on making in my car. I've been out of school for awhile so appologies for the simplicity of this question. Can someone help show me how to calculate this question with the answer included? The car get's 19 miles per gallon. Gasoline here is about 95 cents a litre. We don't use gallons. And the trip is 2500 miles. How much will the total cost of gasoline be for that trip? thank you!!
