Final answer:
To determine the price per liter of unleaded and supreme gas, set up a system of linear equations using the provided information and solve it.
Step-by-step explanation:
To find the price per liter of each kind of gas, we can set up a system of linear equations based on the information provided. Let u represent the price per liter of unleaded gas and s represent the price per liter of supreme gas.
The first equation comes from the statement that 2 liters of unleaded gas and 3 liters of supreme gas cost a total of $2.52, which can be written as:
2u + 3s = 2.52
The second equation is based on the statement that 5 liters of unleaded gas and 4 liters of supreme gas cost a total of $4.48, so:
5u + 4s = 4.48
Solving this system of equations simultaneously will give us the price per liter of unleaded and supreme gas. This can be done by using substitution or elimination methods.
