If the original quantity is 10 and the new quantity is 13,what is the percent increase

30% Increase

we know 3 is 30% of 10 and 10+3=13 so we know that 13 is a 30% increase of 10.

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
