a.
Assuming that the relationship between cost and number of chairs produced is linear, find an equation that expresses this relationship. Then graph the equation.
a.
Answer to Problem 76E
Explanation of Solution
Calculation:
Assume that the relationship between cost and number of chairs produced is linear, and then the equation that represents this relationship is given as,
To manufacture
To manufacture
Subtract equation
So, the value of
Now, we substitute the value
Put these values of
So, the linear equation that expresses this relationship between cost and number of chairs produced is
The graph of the equation
Hence, the linear equation that expresses this relationship between cost and number of chairs produced is
b.
What is the slope of the line in part
b.
Answer to Problem 76E
It represents the cost per number of chairs.
Explanation of Solution
Calculation:
Since, the equation of the line that has slope
Hence, the slope of the line
c.
What is
c.
Answer to Problem 76E
It represents the monthly fixed cost.
Explanation of Solution
Calculation:
Since, the equation of the line that has slope
Hence, the
