55 more |
Before |
10 u |
5x2 + 55 =
10 u + 55 |
Change |
- 7 u |
- 2x2 - 22 =
- 4 u - 22
|
After |
3 u |
3x2 + 33 =
6 u + 33 |

and wafers in the end |

48 more |
0.7 =
710 25 x 55 = 22
Number of wafers that Aunt Zara gave to Julie = 4 u + 22
If Aunt Zara made another 48 scones in the end, the number of scones and wafers in the end would be the same.
6 u + 33 = 3 u + 48
6 u - 3 u = 48 - 33
3 u = 15
1 u = 15 ÷ 3 = 5
Number of scones that Aunt Zara made
= 10 u
= 10 x 5
= 50
Answer(s): 50
