Cupcake World makes the best cupcakes of all kinds. The graph shows the relationship of cupcakes baked and additional cups of sugar used to bake the cupcakes.
y: 0,10,20,30,40,50,60,70,80
x:0,10,20,30,40,50
What is the rate of change and what does it represent?
The rate of change is
, and represents
the additional cups of sugar used to bake each additional cupcake.
Whats the rate of change tho?
To find the rate of change, we can look at the change in y divided by the change in x.
The change in y is 80 - 0 = 80, and the change in x is 50 - 0 = 50.
So, the rate of change is 80/50 = 1.6.
This means that for every 1 additional cupcake baked, an additional 1.6 cups of sugar are used.
