If f(5)=288.9 when r=0.05 for the function f(t)= pe^rt, then what is the approximate value of p?

The general equation is: f(t)= 

The given equation is: f(5)=288.9 when r = 0.05

Following the general equation, we know the following:

t=5, r = 0.05 and    = 288.9

Substituting all unknowns, we can solve for p

= 288.9

Solving for p,

p = 225

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
