85 more |
Before |
10 u |
5x2 + 85 =
10 u + 85 |
Change |
- 9 u |
- 3x2 - 51 =
- 6 u - 51
|
After |
1 u |
2x2 + 34 =
4 u + 34 |

and croissants in the end |

91 more |
0.9 =
910 35 x 85 = 51
Number of croissants that Aunt Natalie gave to Emily = 6 u + 51
If Aunt Natalie made another 91 macarons in the end, the number of macarons and croissants in the end would be the same.
4 u + 34 = 1 u + 91
4 u - 1 u = 91 - 34
3 u = 57
1 u = 57 ÷ 3 = 19
Number of croissants that Aunt Natalie made
= 10 u + 85
= 10 x 19 + 85
= 190 + 85
= 275
Answer(s): 275
