56 The remaining amount is the combined repeated identity. Make the remaining amount the same. LCM of 5 and 6 is 30.
Amount that Seth had left
=
14 x 36 u
= 9 u
Amount that Seth spent on snacks
= 25 u - 9 u
= 16 u
16 u = 48
1 u = 48 ÷ 16 = 3
Total amount that Seth had at first
= 36 u
= 36 x 3
= $108
Answer(s): $108
