Yesterday, Riordan had 54 muffins and 31 shortbreads. This morning, he sold 19 muffins and bought some more shortbreads. Now he has five times as many shortbreads as muffins. How many shortbreads did he buy today?

+ ? |
| After |
1 u |
5 u |
Number of muffins in the end
= 54 - 19
= 35
1 u = 35
Number of shortbreads in the end
= 5 u
= 5 x 35
= 175
Number of shortbreads that Riordan bought today
= 5 u - 31
= 175 - 31
= 144
