95 more |
Before |
10 u |
5x2 + 95 =
10 u + 95 |
Change |
- 9 u |
- 2x2 - 38 =
- 4 u - 38
|
After |
1 u |
3x2 + 57 =
6 u + 57 |

and shortbreads in the end |

157 more |
0.9 =
910 25 x 95 = 38
Number of shortbreads that Aunt Marion gave to Emma = 4 u + 38
If Aunt Marion made another 157 croissants in the end, the number of croissants and shortbreads in the end would be the same.
6 u + 57 = 1 u + 157
6 u - 1 u = 157 - 57
5 u = 100
1 u = 100 ÷ 5 = 20
Number of shortbreads that Aunt Marion made
= 10 u + 95
= 10 x 20 + 95
= 200 + 95
= 295
Answer(s): 295
