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 macarons
and wafers in the end |
|
78 more |
0.7 =
710 25 x 65 = 26
Number of wafers that Aunt Kathy gave to Yen = 4 u + 26
If Aunt Kathy made another 78 macarons in the end, the number of macarons and wafers in the end would be the same.
6 u + 39 = 3 u + 78
6 u - 3 u = 78 - 39
3 u = 39
1 u = 39 ÷ 3 = 13
Number of macarons that Aunt Kathy made
= 10 u
= 10 x 13
= 130
Answer(s): 130
