- 7 u |
- 2x2 - 32 =
- 4 u - 32

3x2 + 48 =
6 u + 48 |

0.7 =
710 25 x 80 = 32
Number of tarts that Aunt Nicole gave to Tina = 4 u + 32
If Aunt Nicole made another 108 scones in the end, the number of scones and tarts in the end would be the same.
6 u + 48 = 3 u + 108
6 u - 3 u = 108 - 48
3 u = 60
1 u = 60 ÷ 3 = 20
Number of tarts that Aunt Nicole made
= 10 u + 80
= 10 x 20 + 80
= 200 + 80
= 280
Answer(s): 280
