0.8 =
810 =
4512 x 72 = 36
72 - 36 = 36
If Auntie Emily baked another 45 apricot muffins, there would be equal number of blueberry muffins and apricot muffins in the end.
5 u + 36 = 2 u + 45
5 u - 2 u = 45 - 36
3 u = 9
1 u = 9 ÷ 3 = 3
Total muffins that Auntie Emily baked
= 10 u + 72 + 10 u
= 20 u + 72
= 20 x 3 + 72
= 60 + 72
= 132
Answer(s): 132
