0.8 =
810 =
4512 x 30 = 15
30 - 15 = 15
If Auntie Hazel baked another 24 cheese puffs, there would be equal number of banana puffs and cheese puffs in the end.
5 u + 15 = 2 u + 24
5 u - 2 u = 24 - 15
3 u = 9
1 u = 9 ÷ 3 = 3
Total puffs that Auntie Hazel baked
= 10 u + 30 + 10 u
= 20 u + 30
= 20 x 3 + 30
= 60 + 30
= 90
Answer(s): 90
