Question

Seth has a recipe for brownies. He uses 2.5 cups of flour to make 6 brownies. Laura will follow the same recipe. She will make b brownies using f cups of flour. Which equations represents the relationship between band f?

Answer 1

We have the following:

We have that the input variable is the cups of flour (f) and the output variable is the brownies.

Therefore, it would be:

`\begin{gathered} b=(6)/(2.5)f \\ b=(12)/(5)f \\ \end{gathered}`

check:

`b=(12)/(5)\cdot2.5=2.4\cdot2.5=6`
