Step 1
Find the total number of kilometers driven in a week
Multiply [tex]125 km[/tex] by [tex]7[/tex]
[tex]125*7=875\ km[/tex]
Step 2
Find the the amount of gasoline required
we know that
The car's gas mileage is [tex]23\frac{mi}{gal}[/tex]
convert km to miles
[tex]1\ mile=1.60934\ km[/tex]
[tex]875\ km=875/(1.60934)=543.70\ miles[/tex]
Divide [tex]543.70[/tex] miles to [tex]23\frac{mi}{gal}[/tex] to find the number of gallons
[tex]543.70/23=23.64\ gal[/tex]
Step 3
Find the cost
we know that
The gas costs [tex]1.10[/tex] euros per liter
convert gallons to liters
[tex]1\ gal=3,78541\ lt[/tex]
[tex]23.64\ gal=23.64*3.78541=89.48\ liters[/tex]
[tex]89.48*1.10=98.43\ euros[/tex]
convert euros to dollars
[tex]1\ euro=1.26\ dollars[/tex]
[tex]98.43*1.26=\$124.02[/tex]
therefore
the answer is
[tex]\$124.02[/tex]
