15If Auntie Irene baked another 99 vanilla puffs, there would be equal number of blueberry puffs and vanilla puffs in the end.
35 u + 84 = 32 u + 99
35 u - 32 u = 99 - 84
3 u = 15
1 u = 15 ÷ 3 = 5
Total puffs that Auntie Irene baked
= 40 u + 96 + 40 u
= 80 u + 96
= 80 x 5 + 96
= 400 + 96
= 496
Answer(s): 496
