0.8 =
810 =
4513 x 60 = 20
60 - 20 = 40
If Auntie Jean baked another 82 chocolate chip buns, there would be equal number of vanilla buns and chocolate chip buns in the end.
10 u + 40 = 3 u + 82
10 u - 3 u = 82 - 40
7 u = 42
1 u = 42 ÷ 7 = 6
Total buns that Auntie Jean baked
= 15 u + 60 + 15 u
= 30 u + 60
= 30 x 6 + 60
= 180 + 60
= 240
Answer(s): 240
