10 u |
5x2 + 95 =
10 u + 95 |
Change |
- 7 u |
- 2x2 - 38 =
- 4 u - 38

After |
3 u |
3x2 + 57 =
6 u + 57 |

78 more |
0.7 =
710 25 x 95 = 38
Number of scones that Aunt Cathy gave to Fiona = 4 u + 38
If Aunt Cathy made another 78 croissants in the end, the number of croissants and scones in the end would be the same.
6 u + 57 = 3 u + 78
6 u - 3 u = 78 - 57
3 u = 21
1 u = 21 ÷ 3 = 7
Number of scones that Aunt Cathy made
= 10 u + 95
= 10 x 7 + 95
= 70 + 95
= 165
Answer(s): 165
