Answer :
Ted would pay $26.50 for 30 liters of unleaded and 25 liters of supreme gas.
Let x represent the price of unleaded gas and y represent the price of supreme gas.
2 liters of unleaded and 3 liters of supreme cost a total of $2.52. Hence:
2x + 3y = 2.52 (1)
Five liters of unleaded and 4 liters of supreme cost a total of $4.48. Hence:
5x + 4y = 4.48 (2)
Solving equations 1 and 2 simultaneously gives:
x = 0.48, y = 0.52
For 30 liters of unleaded and also filled his car with 25 liters of supreme:
Cost = 30(0.48) + 0.52(25) = $26.5
Ted would pay $26.50 for 30 liters of unleaded and 25 liters of supreme gas.
