50 more |
Before |
10 u |
5x2 + 50 =
10 u + 50 |
Change |
- 9 u |
- 3x2 - 30 =
- 6 u - 30
|
After |
1 u |
2x2 + 20 =
4 u + 20 |
Comparing puffs
and croissants in the end |
|
59 more |
0.9 =
910 35 x 50 = 30
Number of croissants that Aunt Anna gave to Mary = 6 u + 30
If Aunt Anna made another 59 puffs in the end, the number of puffs and croissants in the end would be the same.
4 u + 20 = 1 u + 59
4 u - 1 u = 59 - 20
3 u = 39
1 u = 39 ÷ 3 = 13
Number of puffs that Aunt Anna made
= 10 u
= 10 x 13
= 130
Answer(s): 130
