During a trip, Sally spent 1/4 of her money on some clothes. She also spent 1/3 of the remaining money on a bag. She then bought a camera which cost $15 more than the bag and had $95 left. How much money did Sally have at first?

at the start, she had x dollars.
clothes: x/4
bag: (3x/4)/3 = x/4
camera: bag+15 = x/4+15
remainder: 95
x  x/4  x/4  (x/4+15) = 95
x/4  15 = 95
x/4 = 110
x = 440
So, she started out with $440
clothes: 110, now has 330
bag: 1/3(330) = 110, now has 220
camera: 125, now has 95
