and puffs at first |

55 more |
Before |
10 u |
5x2 + 55 =
10 u + 55 |
Change |
- 9 u |
- 2x2 - 22 =
- 4 u - 22
|
After |
1 u |
3x2 + 33 =
6 u + 33 |
Comparing muffins
and puffs in the end |
|
68 more |
0.9 =
910 25 x 55 = 22
Number of puffs that Aunt Kathy gave to Winnie = 4 u + 22
If Aunt Kathy made another 68 muffins in the end, the number of muffins and puffs in the end would be the same.
6 u + 33 = 1 u + 68
6 u - 1 u = 68 - 33
5 u = 35
1 u = 35 ÷ 5 = 7
Number of muffins that Aunt Kathy made
= 10 u
= 10 x 7
= 70
Answer(s): 70
