0.8 =
810 =
4512 x 84 = 42
84 - 42 = 42
If Auntie Jean baked another 66 strawberry buns, there would be equal number of chocolate chip buns and strawberry buns in the end.
5 u + 42 = 2 u + 66
5 u - 2 u = 66 - 42
3 u = 24
1 u = 24 ÷ 3 = 8
Total buns that Auntie Jean baked
= 10 u + 84 + 10 u
= 20 u + 84
= 20 x 8 + 84
= 160 + 84
= 244
Answer(s): 244
