Answer:
1/5
Step-by-step explanation:
You want k so that ...
y = kx
You are told that y=6 when x=30, so ...
6 = k·30
6/30 = k = 1/5
The constant of proportionality is 1/5.
y = (1/5)x
Answer:
5
Step-by-step explanation:
Divide 30 by 6, since this will find the number of chairs she can paint in 1 minute:
30/6
= 5
So, the constant of proportionality is 5, since she can paint 5 chairs in a minute.
