Answer:

66000

Step-by-step explanation:

since the graph represents a proprtional relationship the equation of the graph must be written this way :

y = ax where  a is the slope

you can notice that 2 goes with 24000

so 24000 = 2a then x = 24000/2= 12000

so a = 12000

now replace x with 5.5

y= 5.5*12000=66000
