0.8 =

4514 x 28 = 7
28 - 7 = 21
If Auntie Dana baked another 43 vanilla puffs, there would be equal number of banana puffs and vanilla puffs in the end.
15 u + 21 = 4 u + 43
15 u - 4 u = 43 - 21
11 u = 22
1 u = 22 ÷ 11 = 2
Total puffs that Auntie Dana baked
= 20 u + 28 + 20 u
= 40 u + 28
= 40 x 2 + 28
= 80 + 28
= 108
Answer(s): 108
