To Find: The cost of 3.2 GHz computer system.
Answer to Problem 43E
The cost of the 400 MHz computer system is
Explanation of Solution
Given:
The computer factory sells 2.4 GHz computer system for $595 and 2.8GHz for $619.
Calculation:
Consider that the computer factor is selling a 300 MHz computer system of $595 and 350 MHz system for $619.
Consider
Then, the linear relation between x and y is the equation of the line that passes through the point
Then, the equation of the line is,
Then, the cost of 400 MHz is obtained by the substitution
Then, the cost of the 400 MHz computer system is
