Can u help me on the last one??

y=22

Step-by-step explanation:

the denominator of the first fraction is multiplied by 2 to get the denominator of the second fraction, so the numerator of the first fraction has to be multiplied by 2 to keep the two fractions equal to each other.

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
