So we need to find an equation that relates the number of drops of vanilla v in terms of the number of cups. We know that each cup contains 2 drops of lemon oil and that for each drop of this oil Becca adds 3 drops of vanilla. Then the number of vanilla drops v in a cup of perfume c is given by the product between the number of lemon oil drops in the cup and the number of vanilla drops per drop of lemon oil:
[tex]2\cdot3=6[/tex]
So if each cup has 6 drops of vanilla we get:
[tex]v=6c[/tex]
Where the vanilla drops depends on the number of cups she wants to make. This means that v is the dependent variable and c is the independent variable. Then the answers to the three boxes in order are:
6
c
v
