Chapter 3, Problem 17MCQ
Solution

(a)

To find: The solution of the system.

The solution of the system is equal to 4,871 .

Given information:

An ordinary refrigerator costs $503 and has an estimated annual operating cost of $92 . An energy efficient model cost $615 with an estimated annual operating cost of $64 .

Calculation:

Let x be the number of years.

Let y be the total cost of the refrigerator.

An ordinary refrigerator costs $503 and has an estimated annual operating cost of $92 .

It can be represented in equation below:

  y=92x+503...1

An energy efficient model cost $615 with an estimated annual operating cost of $64 .

It can be represented in equation below:

  y=64x+615...2

Solve the equation (1) and (2).

Substitute the value of y from equation (2) in the equation (1) and solve for x :

  64x+615=92x+50392x64x=61550328x=112x=4

Substitute x=4 in the equation (1) and calculate the value of y :

  y=924+503=368+503=871

Therefore, the solution of the system is 4,871 .

(b)

To find: The meaning of the solution of the system.

After 4 years the total cost of the refrigerator will be $871 .

Given information:

An ordinary refrigerator costs $503 and has an estimated annual operating cost of $92 . An energy efficient model cost $615 with an estimated annual operating cost of $64 .

Calculation:

Let x be the number of years.

Let y be the total cost of the refrigerator.

From part (a) and (b),

  x=4,y=871

It means that after four years the total cost of the refrigerator will be $871 .
