fencing. She has 9248 square feet of property available to fence. Choose the
equation that you would use, after substitution, to take the derivative of.

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

i got 10.28 but that rounds up to 10.3
