djverab [1.8K]

Answer:

In  this case, the country that produces rye will produce 24 million bushels per week, and the country that produces jeans will produce 64  million pairs per week.

Explanation:

Total labor hour = 4 million hour

Number of bushes produce in 1 hour = 6

⇒total bushes produce = 6*4 = 24 million

∴ we get

The country that produces rye will produce 24 million bushels per week

Now,

Total labor hour = 4 million hour

Number of pairs produce in 1 hour = 16

⇒total bushes produce = 16*4 = 64 million

∴ we get

The country that produces jeans will produce 64  million pairs per week.
