Answer:

$ 452.80

Step-by-step explanation:

Given,

The regular payment per hour for each employee = $ 8.20,

∵ Number of regular hours = 10,

Thus, wages for each employee in regular hours = 10 × 8.20 = $ 82,

Also, the overtime charges per hour = 8.20 + 2.20 = $ 10.4,

∵ Number of overtime hours = 3,

Thus, the overtime charges for each employee = 3 × 10.4 = $ 31.2,

∴ Total earning of each employee = 82 + 31.2 = $ 113.2,

Now, number of employees = 4,

Hence, the total earning of all employees = 4 × 113.2 = $ 452.8
