Question 65767This question is from textbook Beginning Algebra
: The cost of the producing a number of items x is given by C=mx+b, in which b is the fixed cost and m is the variable cost (the cost of producing one more item).
a). If the fixed cost is $40.00 and the variable cost is $10.00, write the cost equation.
b). Graph the cost equation.
The equation I came up with is C=10x+40. However I have not a clue on if this is correct and how to graph this equation. Could you please give some assistance. Thanks.

You can put this solution on YOUR website! The cost of the producing a number of items x is given by C=mx+b, in which b is the fixed cost and m is the variable cost (the cost of producing one more item).
a). If the fixed cost is $40.00 and the variable cost is $10.00, write the cost equation.
b). Graph the cost equation.
The equation I came up with is C=10x+40.
You're right about the equation, so give yourself a high five!
To graph this, give yourself a scale of 1 unit per 10. (Just count by tens)
Plot a point on the y axis at 40, then use the slope, m=rise/run, go up 10 and right 1 and plot another point at (1,50). Connect the points and you have a line.
Happy Calculating!!!
