56 The remaining amount is the combined repeated identity. Make the remaining amount the same. LCM of 7 and 6 is 42.
Amount that Xavier had left
=
14 x 48 u
= 12 u
Amount that Xavier spent on drinks
= 35 u - 12 u
= 23 u
23 u = 46
1 u = 46 ÷ 23 = 2
Total amount that Xavier had at first
= 48 u
= 48 x 2
= $96
Answer(s): $96
