0.2 =
210 =
1517 x 84 = 12
84 - 12 = 72
If Auntie Nora baked another 84 cherry puffs, there would be equal number of apricot puffs and cherry puffs in the end.
30 u + 72 = 28 u + 84
30 u - 28 u = 84 - 72
2 u = 12
1 u = 12 ÷ 2 = 6
Total puffs that Auntie Nora baked
= 35 u + 84 + 35 u
= 70 u + 84
= 70 x 6 + 84
= 420 + 84
= 504
Answer(s): 504
