Answer 1

Hi Edward,

 

1 gallon = 3.7854 liters

 

1) First convert the amount of gas in your car from gallons to liters.

 

(23 gallons) * (3.7854 liters / 1 gallon) = 87.0642 liters

 

2) Next "convert" from liters to Mexican dollars.

 

(87.0642 liters) * (Mex$7.73 / 1 liter) = Mex$673.0062

 

3) Finally, convert from Mex$ to $.

 

(Mex$673.0062) * ($1 / Mex$12.4823) = $53.9168
