Write function pay() that takes as input an hourly wage and the number of hours an employee worked in the last week. The function should compute and return the employees pay. Overtime work should be paid in this way: Any hours beyond 40 but less than or equal 60 should be paid at 1.5 times the regular hourly wage. Any hours beyond 60 should be paid at 2 times the regular hourly wage.
