4) 3d

5) 2c

6) 6a

7) 3b

8) 0

Step-by-step explanation:

1) 3a + a = 4a

2) 4c + 2c + c = 7c

3) 3b + 3b + 2b = 8b

4) 4d – d = 3d

5) 3c + 4c – 5c = 2c

6) 4a – 2a + 4a = 6a

7) b + 4b – 3b + b = 3b

8) 2c – 4c + 3c - c = 0

x

step-by-step explanation:

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
