If the constraint 3_x1 + 4_x2 + (d_1-) - (d₁₊) = 250 measures hours, then A) 3_x1 + 4_x2 is equal to the actual time spent. B) if d₁- is equal to 25, then 3_x1 + 4_x2 must equal 25. C) overtime could be represented by d_1-. D) hours can take only an integer value.

The term (d1-) - (d1+) represents any extra time worked beyond the normal hours, while 3x1 + 4x2 represents the actual time spent. Therefore, the constraint 3x1 + 4x2 + (d1-) - (d1+) = 250 measures the total time spent, whether it's within normal hours or with overtime.
