A tennis star was hired to sign autographs at a convention.

Question

She was paid $4000 plus 3% of all admission fees collected at the door. The total amount she received for the day was $4840. Find the total amount collected at the door.

Answer 1

let x be total fees collected at door

 

4000 + .03x = 4840

 

.03x = 4840 - 4000

 

.03x = 840

 

x = $28,000
