Question

Maria spent 2/5 of her money on a book and 1/6 of the remainder on a P.E. uniform. If the book costs P105 more than the P.E. uniform, how much money did she have at first?

Answer 1

Starting with x,

2x/5 = b
1/6 (3/5 x) = u
b = u+105

Now just solve for x by substituting in the values of b and u

Answer 2
