35If Auntie Sarah baked another 68 strawberry puffs, there would be equal number of apple puffs and strawberry puffs in the end.
10 u + 44 = 6 u + 68
10 u - 6 u = 68 - 44
4 u = 24
1 u = 24 ÷ 4 = 6
Total puffs that Auntie Sarah baked
= 15 u + 66 + 15 u
= 30 u + 66
= 30 x 6 + 66
= 180 + 66
= 246
Answer(s): 246
