The number of macarons that Liam had remains unchanged.
If Liam had another 12 macarons in the end, the number of macarons that Ivory and Liam had would be the same.
4 u - 6 = 1 u + 12
4 u - 1 u = 12 + 6
3 u = 18
1 u = 18 ÷ 3 = 6
Total number of macarons
= 4 u + 1 u
= 5 u
= 5 x 6
= 30
Answer(s): 30
