Final answer:

The artist paints at a constant rate of 2 paintings every 3 hours. By continuing this pattern, we deduce that the artist will paint 8 paintings in 12 hours, which corresponds to option B.

Step-by-step explanation:

The student's question pertains to finding a relationship between the number of hours worked and the number of paintings completed by an artist, which is a typical problem in linear relationships in mathematics. By observing the provided table, we can see that the artist paints 2 paintings in 3 hours, and 4 paintings in 6 hours, indicating that the artist paints at a constant rate of 2 paintings every 3 hours. To complete the table and find out how many paintings the artist will paint in 12 hours, we simply extend this pattern

Here's the completed part of the table.

  • 9 hours - 6 paintings
  • 12 hours - 8 paintings (answer: B)

To confirm, we use the ratio of paintings to hours which is 2 paintings per 3 hours. This is a linear relationship with a constant rate of 2/3 paintings per hour.

Hours(Painting Rate) = Number of Paintings

3(2/3) = 2

6(2/3) = 4

9(2/3) = 6

12(2/3) = 8

It can be seen that in 12 hours, the artist will complete 8 paintings (B).
