Question 1148018
let a = His original amt
David spent 25% of his money in one shop
Now he has .75a remaining
 He now has and then spent one third of the remainder in another shop.
Now he has {{{2/3}}}(.75a)
 If he had $5.50 left, how much had he at first?
{{{2/3}}}(.75a) = 5.50
2(.25a) = 5.50
.5a = 5.50
a = 5.50/.5
a = $11.00 at first
