95 more |
Before |
10 u |
5x2 + 95 =
10 u + 95 |
Change |
- 9 u |
- 3x2 - 57 =
- 6 u - 57
|
After |
1 u |
2x2 + 38 =
4 u + 38 |
Comparing croissants
and puffs in the end |
|
65 more |
0.9 =
910 35 x 95 = 57
Number of puffs that Aunt Fiona gave to Dana = 6 u + 57
If Aunt Fiona made another 65 croissants in the end, the number of croissants and puffs in the end would be the same.
4 u + 38 = 1 u + 65
4 u - 1 u = 65 - 38
3 u = 27
1 u = 27 ÷ 3 = 9
Number of puffs that Aunt Fiona made
= 10 u + 95
= 10 x 9 + 95
= 90 + 95
= 185
Answer(s): 185
