Question

Monty mixed red and yellow paint to make certain shade of paint. For every 2 ounces of red paint he needs 8 ounces of yellow paint. Identify the constant of proportionality. Describe what it represents.

Answer 1

4; see explanation

Explanation:

Let k equal the constant of proportionality, y equal the amount of yellow paint, and x equal the amount of red paint (in ounces).

k = y/x

k = 8/2

k = 4

Therefore, the constant of proportionality is 4 (AKA 4/1). This represents the amount of ounces of yellow paint needed per ounce of red paint.
