Plz help I can’t solve it

i think 10 cause 5+5 =10 sorry if it is wrong

Step-by-step explanation:

Wouldn't the answer just be 10% because everytime it moves, it increases by 10

correct answer:

i^31 = -i

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
