You would spend $63.58 on gas per week.
Step-by-step explanation:
Given,
Distance per day = 117 km
Distance in a week = 117*7 = 819 km
1 km = 0.6214 mile
819 km = 819*0.6214 = 508.93 miles
Car's mileage = 42.0 mi/gallons
Let,
x be the gallons for 508.93 miles
x gallons =
Therefore,
12.12 gallons of gas is needed for one week.
1 US gallon = 3.785 liters
12.12 gallons = 12.12*3.785
12.12 gallons = 45.87 liters
Cost of gas per liter = 1.10 euro
Cost of 45.87 liters = 1.10*45.87 = 50.457 euros
1 euro = $1.26
50.457 euros = 1.26*50.457 = $63.58
You would spend $63.58 on gas per week.
