Mega mart collects a sales tax equal to 1/16 of the retail price.

Lets take some example

Suppose retail price = $16 then tax =

retail price = $32 then tax =

retail price = $48 then tax =

retail price = $64 then tax =

From this we conclude that ,

So, the amount of tax collected proportional to the cost of an item before tax is added

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

can you rephrase the question ? it is unclear : -)
