Problema Solution
Ian spent 3/5 of his money on a book and 1/4 of the remainder on a pen. If the book costs P350 more than the pen, how much money did the boy have at first?
Answer provided by our tutors
let x = the total money Ian had
the cost of the book is: (3/5)x
the cost of the pen is: (1/4)x
(3/5)x = 350 + (1/4)(x - (3/5)x)
by solving we find
x = $700
