23 The remaining amount is the combined repeated identity. Make the remaining amount the same. LCM of 7 and 3 is 21.
Amount that Will had left
=
14 x 24 u
= 6 u
Amount that Will spent on balloons
= 14 u - 6 u
= 8 u
8 u = 64
1 u = 64 ÷ 8 = 8
Total amount that Will had at first
= 24 u
= 24 x 8
= $192
Answer(s): $192
