A multinational company operates in a jurisdiction with complex employment laws. The company recently underwent a merger with another company, resulting in the transfer of employees from the acquired company to the acquiring company. The employment laws require the acquiring company to recognize the length of service of the transferred employees for the purpose of calculating benefits. The acquiring company offers a progressive vacation policy based on years of service, as follows:

•Employees with 1-5 years of service: 10 days of vacation                                                

•Employees with 6-10 years of service: 15 days of vacation 

•Employees with 11-15 years of service: 20 days of vacation 

•Employees with 16-20 years of service: 25 days of vacation 

•Employees with over 20 years of service: 30 days of vacation.

The acquired company had 50 employees with varying lengths of service. Calculate the total number of vacation days each employee is entitled to in the acquiring company, considering their length of service from the acquired company.
