Let the original amount be $x

Amount left after first episode

= x/2 - 1

amount left after lunch

= (x/2-1)/2 - 2

amount left after buying book

= [(x/2-1)/2 - 2]/2

amount left after buying fudge

= [(x/2-1)/2 - 2]/2 - 3

then[(x/2-1)/2 - 2]/2 - 3 = 1

[(x/2-1)/2 - 2]/2 = 4

[(x/2-1)/2 - 2] = 8

(x/2-1)/2 = 10

x/2 - 1 = 20

x/2 = 21

x = 42
