Anthony tedesco sold his bike and accessories for $315. if he received 8 times as money for the bike as he did for the accessories , find how much money he received for the bike.. ?

  $280 for the bike

Step-by-step explanation:

If the relative values were ...

  bike : accessories = 8 : 1

Then the ratio of the bike to the whole amount is ...

  bike : total sale = 8 : (8+1) = 8 : 9

That is, the money Tedesco received for the bike is 8/9 of the total he received:

  bike money = (8/9)×$315 = $280
