0.8 =
810 =
4512 x 78 = 39
78 - 39 = 39
If Auntie Gwen baked another 60 apricot muffins, there would be equal number of strawberry muffins and apricot muffins in the end.
5 u + 39 = 2 u + 60
5 u - 2 u = 60 - 39
3 u = 21
1 u = 21 ÷ 3 = 7
Total muffins that Auntie Gwen baked
= 10 u + 78 + 10 u
= 20 u + 78
= 20 x 7 + 78
= 140 + 78
= 218
Answer(s): 218
