The value of a professional basketball player's autograph rose 10% in the last year. It is now worth $286.00. What was it worth a year ago?

Respuesta :

It was worth $260 a year ago. The $286.00 is 110% because it has increased (added) 10% so 100% + 10% = 110%. Then you divide $286 by 110, resulting in 2.6. Next you multiply 2.6 by 100 to get back to 100% and that equals $260
