and puffs at first |

65 more |
Before |
10 u |
5x2 + 65 =
10 u + 65 |
Change |
- 9 u |
- 3x2 - 39 =
- 6 u - 39
|
After |
1 u |
2x2 + 26 =
4 u + 26 |
Comparing muffins
and puffs in the end |
|
62 more |
0.9 =
910 35 x 65 = 39
Number of puffs that Aunt Eva gave to Cindy = 6 u + 39
If Aunt Eva made another 62 muffins in the end, the number of muffins and puffs in the end would be the same.
4 u + 26 = 1 u + 62
4 u - 1 u = 62 - 26
3 u = 36
1 u = 36 ÷ 3 = 12
Number of muffins that Aunt Eva made
= 10 u
= 10 x 12
= 120
Answer(s): 120
