In the world financial crisis, it is difficult for college students to find jobs. Xiao Wang started his own business, opened a factory and recruited 28 workers. A worker can produce 14 workers every day.
Suppose x workers produce screws, then 28-x workers produce nuts.
Production of 14x screws and 2 1× (28-x) nuts every day; Get the equation:
2× 14x=2 1×(28-x),
28x=588-2 1x,
28x+2 1x=588,
49x=588,
? x = 12;
Then the workers who make nuts are: 28- 12= 16 (people).
Answer: 12 people make screws and 16 people make nuts.
