85 more |
Before |
10 u |
5x2 + 85 =
10 u + 85 |
Change |
- 7 u |
- 2x2 - 34 =
- 4 u - 34
|
After |
3 u |
3x2 + 51 =
6 u + 51 |

93 more |
0.7 =
710 25 x 85 = 34
Number of biscuits that Aunt Jean gave to Abi = 4 u + 34
If Aunt Jean made another 93 scones in the end, the number of scones and biscuits in the end would be the same.
6 u + 51 = 3 u + 93
6 u - 3 u = 93 - 51
3 u = 42
1 u = 42 ÷ 3 = 14
Number of scones that Aunt Jean made
= 10 u
= 10 x 14
= 140
Answer(s): 140
