Question 1105657: Hi
bob spent $720 on a camera and 2/7 of his remaining salary on a watch. He still had $240 left.
how much did he spend altogether.
Thanks Answer by greenestamps(13214) (Show Source):
2/7 of what he had left after buying the camera is what he spent on the watch, so the $240 he has left at the end is 5/7 of what he had after buying the camera.
He had $336 left after buying the camera, and $240 left after buying the watch, so the cost of the watch was $96.
