1014 Number of shortbreads that Jen sold in the afternoon = 10 u
Number of shortbreads that Jen sold in the evening = 3 u
Number of more shortbreads that Jen sold in the afternoon than in the evening
= 10 u - 3 u
= 7 u
7 u = 28
1 u = 28 ÷ 7 = 4
Total number of shortbreads that Jen made
= 14 u
= 14 x 4
= 56
Answer(s): 56
