A certain car uses 7.2 L/100 km in city driving and 5.4 L/100 km in highway driving. If 36 L of gas are used in travelling 595 km. how many kilometres were driven in the city, and how many were driven on the highway (assuming that only the given rates of usage were actually used, to the nearest km)?

First determine the equations required to solve the system then solve the system graphically. Check the solutions you find by inserting them into the original equations.

8. A certain car uses $7.2\mathrm{L}/100\mathrm{km}$ in city driving and $5.4\mathrm{L}/100\mathrm{km}$ in highway driving. If 36 L of gas are used in travelling $598\mathrm{km}$, how many kilometres were driven in the city, and how many were driven on the highway (assuming that only the given rates of usage were actually used, to the nearest $\mathrm{km}$ )? First determine the equations required to solve the system then solve the system graphically. Check the solutions you find by inserting them into the original equations.
