3. The United States produces more manufactured silk articles than any other country, but is entirely dependent on foreign nations for its raw-silk supply. During 1919 the United States imported 44,800,000 lb. of raw silk, of which total Japan furnished 33,700,000 lb., China, 9,000,000 lb., and European countries, the remainder. What per cent of the silk imports came from Japan? from China? from Europe?

4. The total value of the raw silk imported in 1919 was $329,338,872, of which amount Japan received 80%. How much did Japan alone receive for its raw-silk exportations to the United States?

5. The wages of the Japanese workers who reel the silk from the cocoons range from $.50 to $1 for a day that varies in length from 10 hr. to 14 hr. How long would it take one of these workers to earn $30 (which is about the average weekly wage of an American worker) if he is paid $.80 a day and works 6 da. a week?

6. In China the wages average $.30 a day of from 12 hr. to 14 hr. How long would it take a Chinese silk worker to earn $30, if he works 6 da. per week?

7. In 1920 the price of raw silk rose to $16.80 a pound but later dropped to $10.20 a pound. What was the per cent of decrease?

8. In 1920 the United States produced $500,000,000 worth of silk products, as against $100,000,000 worth of products in 1900, and $250,000,000 worth in 1915. What was the per cent of increase in production in 1920 over that of 1900? over that of 1915?

9. In 1900 our annual exports of silk goods amounted to $250,000. In 1918 we exported $20,000,000 worth of such goods. Find the per cent of increase.
