0.8 =

4512 x 16 = 8
16 - 8 = 8
If Auntie Jen baked another 23 cranberry buns, there would be equal number of cherry buns and cranberry buns in the end.
5 u + 8 = 2 u + 23
5 u - 2 u = 23 - 8
3 u = 15
1 u = 15 ÷ 3 = 5
Total buns that Auntie Jen baked
= 10 u + 16 + 10 u
= 20 u + 16
= 20 x 5 + 16
= 100 + 16
= 116
Answer(s): 116
