A jewelry maker is designing a crown. The crown must have at least 45 gems, using only emeralds, rubies, and diamonds. The number of rubies must be 1 less than 3 times the number of emeralds. The number of diamonds must be 4 less than the number of rubies. Which inequality could the jewelry maker use to find the fewest number of emeralds, x, that can be placed on the crown? A. x - 4 + 3x - 1 + x ≥ 45
B. 3x - 1 + 3x - 4 ≥ 45
C. x + 3x - 1 + 3x - 1 - 4 ≥ 45
D. 3x - 1 + 3x - 1 - 4 ≥ 45
