0.8 =
810 =
4523 x 51 = 34
51 - 34 = 17
If Auntie Cindy baked another 33 strawberry puffs, there would be equal number of cranberry puffs and strawberry puffs in the end.
5 u + 17 = 3 u + 33
5 u - 3 u = 33 - 17
2 u = 16
1 u = 16 ÷ 2 = 8
Total puffs that Auntie Cindy baked
= 15 u + 51 + 15 u
= 30 u + 51
= 30 x 8 + 51
= 240 + 51
= 291
Answer(s): 291
