4512 x 66 = 33
66 - 33 = 33
If Auntie Kylie baked another 51 cherry muffins, there would be equal number of cranberry muffins and cherry muffins in the end.
5 u + 33 = 2 u + 51
5 u - 2 u = 51 - 33
3 u = 18
1 u = 18 ÷ 3 = 6
Total muffins that Auntie Kylie baked
= 10 u + 66 + 10 u
= 20 u + 66
= 20 x 6 + 66
= 120 + 66
= 186
Answer(s): 186
