Chapter 1, Problem 28RE

(a)

To determine

To graph: The function C as the function of time t and also determine the nature of the plotting whether it is linear, quadratic or exponential, if the publishing cost C of Duffin House with time t is analyzed by the CEO as follows,

Year t	$0$	$1$	$2$	$3$	$4$	$5$
Cost $C\left(t\right)$	$\$5.42$	$\$5.10$	$\$5.00$	$\$5.12$	$\$5.40$	$\$5.88$

(b)

To determine

To calculate: The differences $C\left(1\right)-C\left(0\right),C\left(2\right)-C\left(1\right)\mathrm{\dots \dots .}\text{and }C\left(5\right)-C\left(4\right)$ and determine its significance, if the publishing cost C of Duffin House with time t is analyzed by the CEO as follows,

Year t	$0$	$1$	$2$	$3$	$4$	$5$
Cost $C\left(t\right)$	$\$5.42$	$\$5.10$	$\$5.00$	$\$5.12$	$\$5.40$	$\$5.88$

(c)

To determine

The next year’s publishing cost, if the publishing cost C of Duffin House with time t is analyzed by the CEO as follows,

Year t	$0$	$1$	$2$	$3$	$4$	$5$
Cost $C\left(t\right)$	$\$5.42$	$\$5.10$	$\$5.00$	$\$5.12$	$\$5.40$	$\$5.88$
