0.4 =
410 =
2518 x 40 = 5
40 - 5 = 35
If Auntie Nora baked another 79 strawberry muffins, there would be equal number of cheese muffins and strawberry muffins in the end.
35 u + 35 = 24 u + 79
35 u - 24 u = 79 - 35
11 u = 44
1 u = 44 ÷ 11 = 4
Total muffins that Auntie Nora baked
= 40 u + 40 + 40 u
= 80 u + 40
= 80 x 4 + 40
= 320 + 40
= 360
Answer(s): 360
