Answer:
400,000
Explanation:
7% of what number = 28,000
(0.07)(X) = 28,000
X = 400,000
(which is less than 700,000. But that makes sense because not everyone living in Michael's city is necessarily part of the labor force. Some could be kids in school, others grandparents who have retired, others people who stay at home and don't work.)
