While in europe, if you drive 123 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 31.0 mi/gal ? assume that 1euro=1.26dollars.

$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.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
