Answer: $28000 was collected at the door.
Step-by-step explanation:
Let x represent the total amount collected of admission feets collected at the door.
She was paid $3000 plus 2% of all admission fees collected at the door. This means that the total amount she was paid for collecting x admission fees at the door is expressed as
3000 + 2/100 × x
= 3000 + 0.02x
The total amount she received for the day was $3560. It means that
3000 + 0.02x = 3560
0.02x = 3560 - 3000
0.02x = 560
x = 560/0.02
x = 28000
