Number of cups of apple juice (A) is proportional to the number of cups of lemon lime soda (L).
A ∝ L
A = kL
Here 'k' is the proportionality constant.
k =
=
Therefore, ratio of the number of cups of apple juice to the number of cups of lemon lime soda is 6 : 1.
Hey, there! For this question, we can just start by plugging in the known values. can be rewritten as
.
Combine like terms:
If you add x to , x will become
, which means that x/2 + x = 3/2x.
-->
If you rearrange this, then your answer will be option b. Hope this helps.
