0.6 =
610 =
3513 x 18 = 6
18 - 6 = 12
If Auntie Betty baked another 40 cherry muffins, there would be equal number of cheese muffins and cherry muffins in the end.
10 u + 12 = 6 u + 40
10 u - 6 u = 40 - 12
4 u = 28
1 u = 28 ÷ 4 = 7
Total muffins that Auntie Betty baked
= 15 u + 18 + 15 u
= 30 u + 18
= 30 x 7 + 18
= 210 + 18
= 228
Answer(s): 228
