34 The remaining amount is the combined repeated identity. Make the remaining amount the same. LCM of 5 and 4 is 20.
Amount that Nick had left
=
13 x 24 u
= 8 u
Amount that Nick spent on drinks
= 15 u - 8 u
= 7 u
7 u = 35
1 u = 35 ÷ 7 = 5
Total amount that Nick had at first
= 24 u
= 24 x 5
= $120
Answer(s): $120
