Weekdays:
- Total seats per show: 450
- Ticket price after tax: RM12.00 - 25% tax = RM 11.75
- Occupancy rates: 30% for the first day, 40% for the second day, 50% for the third day, and 75% for the fourth day
- Number of weekdays in a year: 365 days

Weekends:
- Total seats per show: 450
- Ticket price after tax: RM14.00 - 25% tax = RM 13.75
- Occupancy rates: 80% for Saturday and 70% for Sunday
= Number of weekends in a year: 52 days

Now let's calculate the gross income for weekdays and weekends separately:

For weekdays:
- Gross income per show = (Total seats (multiply) Ticket price (multiply) Occupancy rate (multiply) Number of weekdays
- Gross income per show = (450 (multiply) RM11.75 (multiply) 0.30 (multiply) 365) + (450 (multiply) RM11.75 (multiply) 0.40 (multiply) 365) + (450 (multiply) RM11.75 (multiply) 0.50 (multiply) 365) + (450 (multiply) RM11.75 (multiply) 0.75 (multiply) 365)

For weekends:
- Gross income per show = (Total seats (multiply) Ticket price (multiply) Occupancy rate) (multiply) Number of weekends
- Gross income per show = (450 (multiply) RM13.75 (multiply) 0.80 (multiply) 52) + (450 (multiply) RM13.75 (multiply) 0.70 (multiply) 52)

Total gross income for weekdays and weekends:
