45If Auntie Cindy baked another 53 banana sandwiches, there would be equal number of chocolate chip sandwiches and banana sandwiches in the end.
5 u + 44 = 2 u + 53
5 u - 2 u = 53 - 44
3 u = 9
1 u = 9 ÷ 3 = 3
Total sandwiches that Auntie Cindy baked
= 10 u + 88 + 10 u
= 20 u + 88
= 20 x 3 + 88
= 60 + 88
= 148
Answer(s): 148
