A woman spent 75 more than 75% of her money in one store. She then spent 75 more than 75% of her remaining money in another store. She did the same in a third store and had only 700 left. How much money did she originally have?

Answer 1

Original money = x

First store -> spent (0.75x + 75)

Second store -> spent [0.75(x - (0.75x + 75)) + 75]

Third store -> spent [0.75[x - 0.75(x - (0.75x + 75)] - 75] + 75

Add all these up, subtract that from x, you get 700
Solve the equation for x.
