Question

A baker can bake 20 cupcakes in two hours, 30 cupcakes in three hours, and 40 cupcakes in four hours. What is the constant rate of change?

Answer 1

A baker can bake 20 cupcakes in two hours, 30 cupcakes in three hours, and 40 cupcakes in four hours.

so, the rate can be calculated as following:

number of cupcakes over the number of hours

So,

`\begin{gathered} (20)/(2)=10 \\ or,(30)/(3)=10 \\ or,(40)/(4)=10 \end{gathered}`
