Question

You are making lemonade. The amount of sugar you need depends on the amount of lemonade mix you use.

Answer 1

Yes, it is proportional.

Answer 2

Answer:

The amount of sugar you need is proportional to the amount of lemonade mix you use.

Step-by-step explanation:

Cups of sugar                               Packets of lemonade mix

    1/3                                                             1

    1                                                                3

    3                                                               9

Ratio of packets of lemonade mix to cups of sugar in all cases is 3.

That is

                $\frac{1}{\frac{1}{3}}=\frac{3}{1}=\frac{9}{3}=3$

Let us take packets of lemonade mix as L and cups of sugar as S.

We have

                       L = 3 S

So the amount of sugar you need is proportional to the amount of lemonade mix you use.
