Yesterday, Pierre had 88 wafers and 19 scones. This morning, he sold 39 wafers and bought some more scones. Now he has twice as many scones as wafers. How many scones did he buy today?

19 |
| Change |
- 39 |
+ ? |
| After |
1 u |
2 u |
Number of wafers in the end
= 88 - 39
= 49
1 u = 49
Number of scones in the end
= 2 u
= 2 x 49
= 98
Number of scones that Pierre bought today
= 2 u - 19
= 98 - 19
= 79
