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=100liters
$1g + $1.5f = $130 

g=130-1.5f  substitute into first equation for g

(130-1.5f)+f=100
130-.5f=100
-.5f=100-130
-.5f=-30
f=-30/-.5
f= 60 liters of fruit juice

substitute into first equation

g+60 = 100liters
g=100-60
g=40 liters of ginger ale

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
