34 The remaining amount is the combined repeated identity. Make the remaining amount the same. LCM of 6 and 4 is 12.
Amount that Flynn had left
=
12 x 14 u
= 7 u
Amount that Flynn spent on drinks
= 9 u - 7 u
= 2 u
2 u = 8
1 u = 8 ÷ 2 = 4
Total amount that Flynn had at first
= 14 u
= 14 x 4
= $56
Answer(s): $56
