3514 x 88 = 22
88 - 22 = 66
If Auntie Jean baked another 87 vanilla sandwiches, there would be equal number of apple sandwiches and vanilla sandwiches in the end.
15 u + 66 = 8 u + 87
15 u - 8 u = 87 - 66
7 u = 21
1 u = 21 ÷ 7 = 3
Total sandwiches that Auntie Jean baked
= 20 u + 88 + 20 u
= 40 u + 88
= 40 x 3 + 88
= 120 + 88
= 208
Answer(s): 208
