Let the original amount be $x
Amount left after first episode
= x/2  1
amount left after lunch
= (x/21)/2  2
amount left after buying book
= [(x/21)/2  2]/2
amount left after buying fudge
= [(x/21)/2  2]/2  3
then[(x/21)/2  2]/2  3 = 1
[(x/21)/2  2]/2 = 4
[(x/21)/2  2] = 8
(x/21)/2 = 10
x/2  1 = 20
x/2 = 21
x = 42
