Solutions

Chapter 2.1, Problem 69E

a.

To determine

To find the function C(x)=1500+3x+0.02x2+0.0001x3 for values of x .

Expert Solution

Answer to Problem 69E

The value of given equation for x=10 is C(10)=1532.1

and for x=100 is C(100)=2100 .

Explanation of Solution

Given: Consider the function C(x)=1500+3x+0.02x2+0.0001x3 .

Calculation:

Plug x=10 in C(x)=1500+3x+0.02x2+0.0001x3

  C(10)=1500+3(10)+0.02(10)2+0.0001(10)3.C(10)=1500+30+2+.1C(10)=1532.1 C(100)=1500+3(100)+0.02(100)2+0.0001(100)3             =1500+300+200+100             =2100

Thus, the value of given equation for x=10 is C(10)=1532.1

and for x=100 is C(100)=2100 .

b.

To determine

Representation of the answers obtained in part a.

Expert Solution

Answer to Problem 69E

The representation of part a answers are the cost to produce 10 yards of fabric and 100 yards of fabric respectively

Explanation of Solution

The answers represent the cost to produce 10 yards of fabric and 100 yards of fabric respectively

c.

To determine

Find the value of the fixed cost.

Expert Solution

Answer to Problem 69E

The number represents C(0)=1500 is the fixed cost.

Explanation of Solution

Given: C(x)=1500+3x+0.02x2+0.0001x3

Plug x=0 in C(x)=1500+3x+0.02x2+0.0001x3

  C(0)=1500+3(0)+0.02(0)2+0.0001(0)3.C(0)=1500

Thus the number represents C(0)=1500 is the fixed cost.
