Answer:
Age Group Number of People 18–24 80 25–31 120 32–38 40 39–45 20
Step-by-step explanation:
The data in each bar is how many people in that group.
So 18-24 has 80 people
25-31 has 120 people
32 -38 has 40 people
39-45 has 20 people
.04, .044, .4, .404, 4.404
Call the production cost 'C', the revenue 'R' and the number of CDs 'n':
C=2000+5n
R=10n
By definition Profit P = R-C, therefore P=10n-2000+5n = 5n-2000.
