Can anyone get me started on this?

Question

A country has 2 regions, the North and South, which are identical in all respects except for the hourly wage and number of workers. The demand for labor in the region is Wn=$20 - .5En and Ws=$20 - .5Es where En and Es are millions of workers. Currently there are 6 million workers in the North and 18 million workers in the South. What is the wage in each region?

Answer 1

barring any exchange or movement between the two regions, and assuming all workers are hired,
Wn=20-.5(18) = 9
Ws=20-.5(6) = 17

Answer 2

Thanks.

Is the first one supposed to equal 11?

Answer 3

right, my bad.
