35If Auntie Tina baked another 48 cranberry muffins, there would be equal number of blueberry muffins and cranberry muffins in the end.
20 u + 24 = 14 u + 48
20 u - 14 u = 48 - 24
6 u = 24
1 u = 24 ÷ 6 = 4
Total muffins that Auntie Tina baked
= 35 u + 42 + 35 u
= 70 u + 42
= 70 x 4 + 42
= 280 + 42
= 322
Answer(s): 322
