Yesterday, Ken had 70 cookies and 30 scones. This morning, he sold 34 cookies and bought some more scones. Now he has five times as many scones as cookies. How many scones did he buy today?

+ ? |
| After |
1 u |
5 u |
Number of cookies in the end
= 70 - 34
= 36
1 u = 36
Number of scones in the end
= 5 u
= 5 x 36
= 180
Number of scones that Ken bought today
= 5 u - 30
