37 =
614 Number of biscuits that Tiffany sold in the morning = 6 u
Number of biscuits that Tiffany sold in the evening = 3 u
Number of more biscuits that Tiffany sold in the morning than in the evening
= 6 u - 3 u
= 3 u
3 u = 18
1 u = 18 ÷ 3 = 6
Total number of biscuits that Tiffany made
= 14 u
= 14 x 6
= 84
