25If Auntie Emily baked another 78 cranberry puffs, there would be equal number of cherry puffs and cranberry puffs in the end.
15 u + 60 = 12 u + 78
15 u - 12 u = 78 - 60
3 u = 18
1 u = 18 ÷ 3 = 6
Total puffs that Auntie Emily baked
= 20 u + 80 + 20 u
= 40 u + 80
= 40 x 6 + 80
= 240 + 80
= 320
Answer(s): 320
