So the first question: Since roses INCREASE as weeds DECREASE we can interpret this as: `roses are inversely proportional to weeds`

Remember how to write an relationship when the elements are inversely proportional? :)
We should have something like this.$$\Large r=\frac{k}{w}$$
Where $\Large k$ is a constant of proportionality that we'll need to solve for.

zepdrix · Answer

To solve for k, we'll need to use information from the chart they provided.

zepdrix · Answer

$$\Large \color{#CC0033}{r=20} \qquad\text{when}\qquad \color{#996666}{w=10}$$$$\Large \color{#CC0033}{r}=\frac{k}{\color{#996666}{w}}$$

zepdrix · Answer

Understand how to find k? :)

savannah_noelle · Answer

Okay if there are 5 weeds would it be 10=k/5?

zepdrix · Answer

Hmm we don't want to use the `5 weeds` part just yet.

We need use the `chart` to find k.
See what I did with the 20 and 10 from the chart? :o

Oh okay, yes I see it
