Sharon is making 100 liters of punch for a party. The punch contains ginger ale (g) and fruit juice (f). The cost of the ginger ale is $1 per liter and the fruit juice is $1.50 per liter. If Sharon spent a total of $130, how many liters of each did she put in the punch?
Which system of equations matches the situation?
g + f = 100 (total amount of punch is 100 liters)
1g + 1.5f = 130 (total cost of punch is $130)
