5x2 + 55 =
10 u + 55 |
Change |
- 7 u |
- 2x2 - 22 =
- 4 u - 22

After |
3 u |
3x2 + 33 =
6 u + 33 |

0.7 =
710 25 x 55 = 22
Number of croissants that Aunt Winnie gave to Gillian = 4 u + 22
If Aunt Winnie made another 81 scones in the end, the number of scones and croissants in the end would be the same.
6 u + 33 = 3 u + 81
6 u - 3 u = 81 - 33
3 u = 48
1 u = 48 ÷ 3 = 16
Number of croissants that Aunt Winnie made
= 10 u + 55
= 10 x 16 + 55
= 160 + 55
= 215
Answer(s): 215
