I MAY NOT BE RIGHT!!

If the notebook is $8 and you spend $18 that means you brought 10 worth of pencils.

50c - 1pencil
$1 - 2 pencils
$1.50 is 3
$2 is 4
$2.50 is 5
$3.00 is 6
$3.50 is 7
$4.00 is 8
$4.50 is 9
$5.00 is 10


Then you have spent $5 on pencils in that and then you double it so you then have 20p for $10 :)) then $10 + 8 is $18 and in the problem you spent $18 x
