599
Step-by-step explanation:
Attendance for first night of the play = 455
If attendance increases by 16 on each night for the next 9night, the total number of increment for the next 9nights = 9×16
= 144
This means that the attendance has increased by 144 in the next 9nights.
Total attendance for the 10nights =
Attendance for first night of the play + increment for the next 9nights
Total attendance for the 10nights = 455+144
= 599
