Question

Determine whether the following scenario represents a direct variation and describe why or why not: It takes 4 painters 8 hours to paint a house and 12 painters 6 hours to paint the same house.

Answer 1

No

Explanation:

It would take 1 painter 32 hours to paint a house (because 4*8=32). If we divide 32 by 12 we get 3, so no, it is not a direct variation because if it was it would only take 3 hours for the 12 painters to paint the house.
