Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
a = number of workers total.
the number who work in the united states is .4 * a
the number who work outside the united states is 150.

.4a + 150 = a

subtract .4a from both sides of the equation to get 150 = a - .4a

simplify to get 150 = .6a

solve for a to get a = 150/.6 = 250

the total number of workers is 250.
