Louis Vuitton is the best-known supplier for bags made of this leather. Epi leather is tanned with plant extracts and then dyed. The dyeing process means the leather comes in many vivid colors and is very shiny. The curing process makes the bags water resistant so they are ideal for everyday use.

The formula for calculating Miles Per Gallon is simply miles driven divided by gallons used. So to calculate the miles driven you take the miles at the end of the tank and subtract the Miles at the start of the tank, and then you divide that by the total gallons of gas used.o to calculate the miles driven you take the miles at the end of the tank and subtract the Miles at the start of the tank, and then you divide that by the total gallons of gas used.
Let's say your vehicle's tank holds 20 gallons and the odometer shows 10,000 miles. Next time you get gas, your vehicle takes in six new gallons to get to F for full. Your odometer shows 10,120 miles. Subtract the 10,000 miles you started with from the 10,120 miles it shows now. That means you went 120 miles on six gallons of gas. Divide the 120 by 6, and you'll come up with 20.
