95 more |
Before |
10 u |
5x2 + 95 =
10 u + 95 |
Change |
- 7 u |
- 2x2 - 38 =
- 4 u - 38
|
After |
3 u |
3x2 + 57 =
6 u + 57 |
Comparing cookies
and croissants in the end |
|
69 more |
0.7 =
710 25 x 95 = 38
Number of croissants that Aunt Jane gave to Kylie = 4 u + 38
If Aunt Jane made another 69 cookies in the end, the number of cookies and croissants in the end would be the same.
6 u + 57 = 3 u + 69
6 u - 3 u = 69 - 57
3 u = 12
1 u = 12 ÷ 3 = 4
Number of cookies that Aunt Jane made
= 10 u
= 10 x 4
= 40
Answer(s): 40
