Answer:
No they are not optimally employed
Step-by-step explanation:
When comparing two employees to see if they are optimally employed we will look at the ratio of their productivity and the ratio of their wages.
Ideally the ratio of their wages should be above the ratio of their productivity for them to be optimally employed.
Productivity ratio of A and B= 15 ÷ 20= 0.75
Wage ratio of A and B= 8 ÷ 12= 0.6666
Wage ratio is less than productivity ratio so the employees are not optimally employed.
