Question

A factory that makes chairs is able to produce between two and four chairs every hour. The factory has already made six chairs today and plans to continue production for six more hours. Which of the following number lines represents the possible number of chairs the factory will have at the end of the day?

Answer 1

The first one.

Explanation:

12+ 6 = 18

24+6=30
