First, you drive 123km per day, and they ask for in a week.
There are 7 days in a week, we have to multiply 123 by 7, which equals 861.
=km per week 861
Now, we need to find out how much cost the gas. Gas cost 1.10 euros per-liter, and this problem wants us to assume that 1euro = 1.26 dollars.
So, we divide 1.10 by 1.26 which is 0.87.
=gas cost 0.87 per liter.
Next, this person goes 31.0 mi/gal per stop.
To get the answer we need to divide 861 the full distance in a week and divide it by how many stops nee to be made which is each 31 mi/gal.
So, 861/31 = 27.77 and now we times 0.87 by 27.77 to get gas cost.
=24.16

Answer:
$146.22 or 116.05 euros
Step-by-step explanation:
In Europe, you drive per day = 123 km
in one week = 123 × 7 = 861 km
Car's gas mileage = 31.0 miles per gallon
1 gallon = 3.8 liters
Car's gas mileage in liters = 31/ 3.8 = 8.16 miles per liter
total gas consumed in a week = 861 ÷ 8.16
= 105.5 liters
Cost of gas = 1.10 euros per liter
Total cost of gas used in a week = 105.5 × 1.10
= 116.05 euros
1 euro = 1.26 dollars
116.05 euros = 1.26 × 116.05
= $146.22
You would spend $146.22 or 116.05 euros on gas in one week.
