Question

Ben is a hairstylist. He mixes red paste

and developer to make hair dye. 30% of
the hair dye is red paste. Ben models the
proportional relationship as y is 30% of x.
Identify what y and x represent in the
proportional relationship.

Answer 1

y represents the red paste and developer, x represents the entire dye.

Explanation:

Since y is 30% of x, and the problem gives us information that 30% of the hair dye is red paste and developer, we can determine that y must represent the 30% of the red paste and developer from all the other things he mixes to get the hair dye.
