Answer:
113.12 dollars
Step-by-step explanation:
From the question we are told that you drive 109km/day and your gas milage = 22miles/gallon
Step 1
We convert 109km to miles
1 km = 0.6214 miles
109km =
109km × 0.6214miles/ 1 km
= 67.7326miles
Step 2
Since the gas mileage = 22miles per gallons, we calculated how many gallons of fuel you used in a day
22 miles = 1 gallon
67.7326 miles = x gallon
Cross Multiply
x gallon × 22 miles = 67.7326 × 1 gallon
x gallons = 67.7326 miles × 1 gallon/22 miles
x gallons = 3.0787545455 gallons
Approximately = 3.08 gallons of gas
Hence, in a day you use 3.08 gallons of gas.
Step 3
We are told that has cost 1.10 euros/ liter
Hence, we convert the amount of gas you used in gallons to liters
1 gallon = 3.785 liters
3.08 gallons = y liters
1 gallon × y liters = 3.08 gallons × 3.785 liters
y liters = 3.08 × 3.785/1
y = 11.6578 liters.
So in a day you use 11.6578 liters of gas.
Step 4
Assume that 1euro=1.26dollars.
We are also told that has = 1.10 euros per liters
We convert the amount in Euros to dollars
1 euro = 1.26 dollars
1.10 euros =
1.10 × 1.26
= 1.386 dollars
Hence gas costs 1.386 dollars per liter
Step 5
Since : 1 liter of gas = 1.386 dollars
11.6578 liters of gas =
= 11.6578 liters × 1.386 dollars/ 1 liter
= 16.1577108 dollars
Therefore, in 1 day, you spend approximately = 16.16 dollars on gas
Step 6
The final step:
We are asked to calculate how much you spent on gas in 1 week
1 week = 7 days
Therefore, if
In 1 day you spend = 16.16 dollars on gas
7 days =
= 7 × 16.16 dollars
= 113.12 dollars
Therefore, the amount money you would spend on gas in one week = 113.12 dollars.
