Weekly Payroll

A payroll system treats every employee as an Employee with a WeeklyPay() method, and each kind of employee overrides it.

Each employee is written as:

• salaried <annual>: earns annual / 52.
• hourly <rate> <hours>: earns rate × hours for the first 40 hours and 1.5 × rate for every hour beyond 40.
• commission <base> <rate> <sales>: earns base + rate × sales.

Implement weekly_payroll(employees).

Input

employees: The employees. Numbers may have decimals.

Output

Return the total weekly pay. Answers within 1e-6 are accepted.

Restricciones

0 ≤ number of employees ≤ 10,000

All numbers are between 0 and 10^7; hours ≤ 100
