90 more |
Before |
10 u |
5x2 + 90 =
10 u + 90 |
Change |
- 9 u |
- 2x2 - 36 =
- 4 u - 36
|
After |
1 u |
3x2 + 54 =
6 u + 54 |
Comparing macarons
and croissants in the end |
|
89 more |
0.9 =
910 25 x 90 = 36
Number of croissants that Aunt Fiona gave to Ivory = 4 u + 36
If Aunt Fiona made another 89 macarons in the end, the number of macarons and croissants in the end would be the same.
6 u + 54 = 1 u + 89
6 u - 1 u = 89 - 54
5 u = 35
1 u = 35 ÷ 5 = 7
Number of macarons that Aunt Fiona made
= 10 u
= 10 x 7
= 70
Answer(s): 70
