Question

After spending $200 of her money on a dress. Lily spent 20% of her remaining money on a bag. She then spent $131 on a pair of shoes. In the end, she had 20% of the original amount Lily had at first. What is the original total amount she had at first?

My work so far:
1/5 saved
4/5 spent includes
$200 + $131 + 1/5 of Remainer = 4/5 of Orginal

Answer 1

(x - 200)(.80) - 131 = .20x
x = 485

check:
start: 485
dress: 200 leaves 285
bag: 57 leaves 228
shoes: 131 leaves 97 = 20% of 485

Answer 2

Thank you, Steve but Algebra hasn't been taught yet in my school so I can't use this. Is there another method?
