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 muffins
and croissants in the end |
|
104 more |
0.9 =
910 25 x 40 = 16
Number of croissants that Aunt Diana gave to Rachel = 4 u + 16
If Aunt Diana made another 104 muffins in the end, the number of muffins and croissants in the end would be the same.
6 u + 24 = 1 u + 104
6 u - 1 u = 104 - 24
5 u = 80
1 u = 80 ÷ 5 = 16
Number of muffins that Aunt Diana made
= 10 u
= 10 x 16
= 160
Answer(s): 160
