56 The remaining amount is the combined repeated identity. Make the remaining amount the same. LCM of 5 and 6 is 30.
Amount that Carl had left
=
13 x 36 u
= 12 u
Amount that Carl spent on snacks
= 25 u - 12 u
= 13 u
13 u = 26
1 u = 26 ÷ 13 = 2
Total amount that Carl had at first
= 36 u
= 36 x 2
= $72
Answer(s): $72
