65 more |
Before |
10 u |
5x2 + 65 =
10 u + 65 |
Change |
- 7 u |
- 2x2 - 26 =
- 4 u - 26
|
After |
3 u |
3x2 + 39 =
6 u + 39 |
Comparing biscuits
and croissants in the end |
|
54 more |
0.7 =
710 25 x 65 = 26
Number of croissants that Aunt Joelle gave to Cindy = 4 u + 26
If Aunt Joelle made another 54 biscuits in the end, the number of biscuits and croissants in the end would be the same.
6 u + 39 = 3 u + 54
6 u - 3 u = 54 - 39
3 u = 15
1 u = 15 ÷ 3 = 5
Number of biscuits that Aunt Joelle made
= 10 u
= 10 x 5
= 50
Answer(s): 50
