45If Auntie Esther baked another 35 vanilla puffs, there would be equal number of cheese puffs and vanilla puffs in the end.
5 u + 27 = 3 u + 35
5 u - 3 u = 35 - 27
2 u = 8
1 u = 8 ÷ 2 = 4
Total puffs that Auntie Esther baked
= 15 u + 81 + 15 u
= 30 u + 81
= 30 x 4 + 81
= 120 + 81
= 201
Answer(s): 201
