Yesterday, Eric had 89 tarts and 14 scones. This morning, he sold 40 tarts and bought some more scones. Now he has twice as many scones as tarts. How many scones did he buy today?

- 40 |
+ ? |
After |
1 u |
2 u |
Number of tarts in the end
= 89 - 40
= 49
1 u = 49
Number of scones in the end
= 2 u
= 2 x 49
= 98
Number of scones that Eric bought today
= 2 u - 14
= 98 - 14
= 84
