1824 Number of shortbreads that Sarah sold in the morning = 18 u
Number of shortbreads that Sarah sold in the evening = 5 u
Number of more shortbreads that Sarah sold in the morning than in the evening
= 18 u - 5 u
= 13 u
13 u = 39
1 u = 39 ÷ 13 = 3
Total number of shortbreads that Sarah made
= 24 u
= 24 x 3
= 72
