Every employee works 7 hours per day every employee works 5 days per week every employee works 49 weeks per year every employee works 245 a0 days per year every employee works 1712 a1 hours per year

All numbers are correct except for the amount of hours per year. Every employee works 1715 hours per year.
This is because you know they work 245 days, so you multiply the number of days by the hours they work per day (245 days x 7 hours = 1715 hours).
