40 more |
Before |
10 u |
5x2 + 40 =
10 u + 40 |
Change |
- 9 u |
- 2x2 - 16 =
- 4 u - 16
|
After |
1 u |
3x2 + 24 =
6 u + 24 |
Comparing croissants
and cupcakes in the end |
|
59 more |
0.9 =
910 25 x 40 = 16
Number of cupcakes that Aunt Kathy gave to Emma = 4 u + 16
If Aunt Kathy made another 59 croissants in the end, the number of croissants and cupcakes in the end would be the same.
6 u + 24 = 1 u + 59
6 u - 1 u = 59 - 24
5 u = 35
1 u = 35 ÷ 5 = 7
Number of croissants that Aunt Kathy made
= 10 u
= 10 x 7
= 70
Answer(s): 70
