60 more |
Before |
10 u |
5x2 + 60 =
10 u + 60 |
Change |
- 9 u |
- 3x2 - 36 =
- 6 u - 36
|
After |
1 u |
2x2 + 24 =
4 u + 24 |

84 more |
0.9 =
910 35 x 60 = 36
Number of croissants that Aunt Fanny gave to Tiffany = 6 u + 36
If Aunt Fanny made another 84 biscuits in the end, the number of biscuits and croissants in the end would be the same.
4 u + 24 = 1 u + 84
4 u - 1 u = 84 - 24
3 u = 60
1 u = 60 ÷ 3 = 20
Number of croissants that Aunt Fanny made
= 10 u + 60
= 10 x 20 + 60
= 200 + 60
= 260
Answer(s): 260
