Given:
cost of gas = $0.78/litre
For each 27 miles Trent's car travels, it would need a gallon
Distance covered = 825 miles
The number of gallons of gas needed to travel 825 miles:
[tex]\begin{gathered} =\text{ }\frac{825\text{ miles}}{27\text{ miles/gallon}} \\ =\text{ }30.56\text{ gallon} \end{gathered}[/tex]Recall that :
[tex]1\text{ litre = 0.264 gallon}[/tex]Hence the volume of gas required in liters:
[tex]\begin{gathered} =\text{ 30.56 gallon }\times\frac{1\text{ litre}}{0.264\text{ gallon}} \\ =\text{ }115.76\text{ litre} \end{gathered}[/tex]The amount of US dollars is thus:
[tex]\begin{gathered} =\text{ 115.76 litres }\times\frac{\text{ \$0.78}}{litre}\text{ } \\ =\text{ \$ 90.29} \\ \approx\text{ \$ 90} \end{gathered}[/tex]It would cost Trent $90 to drive 825 miles
