Step-by-step explanation:
Ben worked for 12 hours.
Total = Normal working hours + overtime working hours
12 hours = 9 hours + 3 hours
Ben is paid £12.40 per hour(normal working hours)
he is paid overtime for the additional hours at a rate of 1.2 times his normal rate of pay.
Amount earned Overtime = 1.2 × £12.40
= £14.88
Total amount earned for 12 hours of work = 9(£12.40) + 3(£14.88)
