0.8 =

4512 x 14 = 7
14 - 7 = 7
If Auntie Gem baked another 28 cheese puffs, there would be equal number of banana puffs and cheese puffs in the end.
5 u + 7 = 2 u + 28
5 u - 2 u = 28 - 7
3 u = 21
1 u = 21 ÷ 3 = 7
Total puffs that Auntie Gem baked
= 10 u + 14 + 10 u
= 20 u + 14
= 20 x 7 + 14
= 140 + 14
= 154
Answer(s): 154
