The correct answer is D.
Keep in mind that the number of workers and the number of days are inversely proportional. It means that with more workers, it takes less time to build a house.
First, find the constant. W (number of workers) × D (days) = 8 × 20 = 160
Then, W × 4 (days) = 160 → W = 40
40 workers are needed to build the house in 4 days!The Absolute Best Books to Ace Algebra
