23 =
1421 Number of puffs that Roshel sold in the morning = 14 u
Number of puffs that Roshel sold in the afternoon = 5 u
Number of more puffs that Roshel sold in the morning than in the afternoon
= 14 u - 5 u
= 9 u
9 u = 72
1 u = 72 ÷ 9 = 8
Total number of puffs that Roshel made
= 21 u
= 21 x 8
= 168
