Answer:
Total number of people lost their jobs = 15
Explanation:
From the given diagram,
When the wage is $ 12,
Total numbers of workers = 33
and
When the wage is $ 18,
Total numbers of workers = 18
So,
Change in workers during the wage increased from $12 to $18 = 33 - 18 = 15
∴ we get
Total number of people lost their jobs = 15
