The cost to produce 100 cupcakes is $126; while the cost to produce 120 cupcakes is $144: Suppose a straight line describes the data.
a) Find and interpret the slope of the cost line.
I know the slope is 9/10. But I don't know the meaning of it.
+37084 The slope is defined as how much the graph rises over how much the graph 'runs' horizontally
rise / run = slope if you graphed this line and looked at an x point then went 10 points to the right, you would see the graph would go up 9 units higher......
This tells you that to produce 10 more cupcakes....it costs 9 more dollars.
+37084 ....as a further interpretation of the cost line When x= 0 (this is when you have produced 0 cupcakes) your start-up, or fixed cost are $36 (the y-axis intercept)
