4516 x 30 = 5
30 - 5 = 25
If Auntie Dana baked another 63 strawberry sandwiches, there would be equal number of apple sandwiches and strawberry sandwiches in the end.
25 u + 25 = 6 u + 63
25 u - 6 u = 63 - 25
19 u = 38
1 u = 38 ÷ 19 = 2
Total sandwiches that Auntie Dana baked
= 30 u + 30 + 30 u
= 60 u + 30
= 60 x 2 + 30
= 120 + 30
= 150
Answer(s): 150
