Problema Solution
A man spent three-fourths of his money and then lost three-fourths of the remainder. He has 6 dollars left. How much money did he start with?
Answer provided by our tutors
let 'x' represent the amount of money he started with
(3/4)x + (3/4)(x - (3/4)x)) + 6 = x
(3/4)x + (3/4)x(1 - (3/4)) + 6 = x
x(3/4)(1 + 1 - (3/4)) + 6 = x
by solving we find
x = $96
