Step-by-step explanation:
___________________________________________________
One method is to use "dimensional analysis" — as follows:

{ Note: The " (
`(30 hr)/(worker)` }" ; as follows below —

→ refers to the "30 hours per worker" — in a "1 week period " ;

→ {as specified in this very question/problem} ; and as follows:
__________________________________________________

→
`$ (5.50)/(hr) * (30 hr)/(worker) * (1,000 workers)/(1)` ;

Note: The following "units" get "canceled out to "1" ; and/or "eliminated" ;

→ The "hr" {"hours"} units get canceled out / eliminately completely;

→ {since: "hr / hr" = " 1 " .} .

→ The "worker(s)" units get canceled out/ eliminated completely;

→ {since: "worker(s) / worker(s)" = " 1 " .} .
______________________________________________________
→ We are left with: " $ ( 5.5 * 30 * 1000 ) " ;

→ " $ ( 5.5 * 30 * 1000 ) " ;
___________________________________________________

→ " $ ( 5.5 * 30 * 1000 ) " ;

= " $ 165, 000 " .

The answer is: " $ 165, 000 " .

Answer 2

1 worker = 30 hours a week
1 worker = 30 x $5.50 a week = $165

1 worker = $165
1000 workers = 165 x 1000 = $165 000
