56 The remaining amount is the combined repeated identity. Make the remaining amount the same. LCM of 5 and 6 is 30.
Amount that Albert had left
=
13 x 36 u
= 12 u
Amount that Albert spent on drinks
= 25 u - 12 u
= 13 u
13 u = 52
1 u = 52 ÷ 13 = 4
Total amount that Albert had at first
= 36 u
= 36 x 4
= $144
Answer(s): $144
