Suppose that the first goal in a GP problem is to make 3 X1 + 4 X2 approximately equal to 36. Using the deviational variables d1− and d1+, the following constraint can be used to express this goal.​ 3 X1 + 4 X2 + d1− − d1+ = 36

If we obtain a solution where X1 = 6 and X2 = 2, what values do the deviational variables assume?

a. d1− = 0, d1+ = 10
b. d1− = 6, d1+ = 0
c. d1− = 5, d1+ = 5
d. d1− = 10, d1+ = 0

Why were most movies from the late 1890s until the early 1930s only filmed in black and white? there were only a few people who could afford the technology to produce color motion pictures back then. audiences did not want color motion pictures until later. the film used to make color motion pictures often overheated, which was a safety hazard, so it was generally not allowed. color films had to be hand-colored, frame by frame.
