55 more |
Before |
10 u |
5x2 + 55 =
10 u + 55 |
Change |
- 9 u |
- 2x2 - 22 =
- 4 u - 22
|
After |
1 u |
3x2 + 33 =
6 u + 33 |
Comparing macarons
and croissants in the end |

53 more |
0.9 =
910 25 x 55 = 22
Number of croissants that Aunt Shiyun gave to Sarah = 4 u + 22
If Aunt Shiyun made another 53 macarons in the end, the number of macarons and croissants in the end would be the same.
6 u + 33 = 1 u + 53
6 u - 1 u = 53 - 33
5 u = 20
1 u = 20 ÷ 5 = 4
Number of macarons that Aunt Shiyun made
= 10 u
= 10 x 4
= 40
Answer(s): 40
