45If Auntie Betty baked another 43 cranberry puffs, there would be equal number of apple puffs and cranberry puffs in the end.
5 u + 28 = 2 u + 43
5 u - 2 u = 43 - 28
3 u = 15
1 u = 15 ÷ 3 = 5
Total puffs that Auntie Betty baked
= 10 u + 56 + 10 u
= 20 u + 56
= 20 x 5 + 56
= 100 + 56
= 156
Answer(s): 156
