45If Auntie Cathy baked another 31 strawberry puffs, there would be equal number of cheese puffs and strawberry puffs in the end.
5 u + 17 = 3 u + 31
5 u - 3 u = 31 - 17
2 u = 14
1 u = 14 ÷ 2 = 7
Total puffs that Auntie Cathy baked
= 15 u + 51 + 15 u
= 30 u + 51
= 30 x 7 + 51
= 210 + 51
= 261
Answer(s): 261
