Yesterday, Andy had 73 scones and 36 shortbreads. This morning, he sold 34 scones and bought some more shortbreads. Now he has twice as many shortbreads as scones. How many shortbreads did he buy today?

Scones |
Shortbreads |

73 |
36 |
| Change |
- 34 |
+ ? |
| After |
1 u |
2 u |
Number of scones in the end
= 73 - 34
= 39
1 u = 39
Number of shortbreads in the end
= 2 u
= 2 x 39
= 78
Number of shortbreads that Andy bought today
= 2 u - 36
= 78 - 36
= 42
