Raymond had $900. He spent 20% of his money on a wireless phone, 45% on a television set, and the rest on a camera. How much money was sent on the camera?
20% of $900 = $180
45% of $900 = $405
180 + 405 = 585
so subtract from the original total (900) and...
= $315
i went the long way to show steps, the shorter way would be to take 35% of $900.
