65 more |
Before |
10 u |
5x2 + 65 =
10 u + 65 |
Change |
- 9 u |
- 2x2 - 26 =
- 4 u - 26
|
After |
1 u |
3x2 + 39 =
6 u + 39 |
Comparing puffs
and croissants in the end |
|
64 more |
0.9 =
910 25 x 65 = 26
Number of croissants that Aunt Tiffany gave to Victoria = 4 u + 26
If Aunt Tiffany made another 64 puffs in the end, the number of puffs and croissants in the end would be the same.
6 u + 39 = 1 u + 64
6 u - 1 u = 64 - 39
5 u = 25
1 u = 25 ÷ 5 = 5
Number of croissants that Aunt Tiffany made
= 10 u + 65
= 10 x 5 + 65
= 50 + 65
= 115
Answer(s): 115
