Before |
10 u |
5x2 + 85 =
10 u + 85 |
Change |
- 9 u |
- 3x2 - 51 =
- 6 u - 51

After |
1 u |
2x2 + 34 =
4 u + 34 |

52 more |
0.9 =
910 35 x 85 = 51
Number of wafers that Aunt Winnie gave to Opal = 6 u + 51
If Aunt Winnie made another 52 scones in the end, the number of scones and wafers in the end would be the same.
4 u + 34 = 1 u + 52
4 u - 1 u = 52 - 34
3 u = 18
1 u = 18 ÷ 3 = 6
Number of wafers that Aunt Winnie made
= 10 u + 85
= 10 x 6 + 85
= 60 + 85
= 145
Answer(s): 145
