3513 x 36 = 12
36 - 12 = 24
If Auntie Risa baked another 44 banana sandwiches, there would be equal number of apple sandwiches and banana sandwiches in the end.
10 u + 24 = 6 u + 44
10 u - 6 u = 44 - 24
4 u = 20
1 u = 20 ÷ 4 = 5
Total sandwiches that Auntie Risa baked
= 15 u + 36 + 15 u
= 30 u + 36
= 30 x 5 + 36
= 150 + 36
= 186
Answer(s): 186
