35If Auntie Risa baked another 50 cheese muffins, there would be equal number of cranberry muffins and cheese muffins in the end.
15 u + 36 = 8 u + 50
15 u - 8 u = 50 - 36
7 u = 14
1 u = 14 ÷ 7 = 2
Total muffins that Auntie Risa baked
= 20 u + 48 + 20 u
= 40 u + 48
= 40 x 2 + 48
= 80 + 48
= 128
Answer(s): 128
