85 more |
Before |
10 u |
5x2 + 85 =
10 u + 85 |
Change |
- 7 u |
- 2x2 - 34 =
- 4 u - 34
|
After |
3 u |
3x2 + 51 =
6 u + 51 |
Comparing muffins
and croissants in the end |
|
75 more |
0.7 =
710 25 x 85 = 34
Number of croissants that Aunt Hilda gave to Pamela = 4 u + 34
If Aunt Hilda made another 75 muffins in the end, the number of muffins and croissants in the end would be the same.
6 u + 51 = 3 u + 75
6 u - 3 u = 75 - 51
3 u = 24
1 u = 24 ÷ 3 = 8
Number of croissants that Aunt Hilda made
= 10 u + 85
= 10 x 8 + 85
= 80 + 85
= 165
Answer(s): 165
