After

1x1 =
1 u |
9 u - 17 |
The number of shortbreads at first is repeated. Make the number of shortbreads at first the same. LCM of 2 and 6 is 6.
Total number of pastries left
= 1 u + 9 u - 17
= 10 u - 17
10 u - 17 = 33
10 u = 33 + 17
10 u = 50
1 u = 50 ÷ 10 = 5
Number of more shortbreads than puffs that Brandon sold
= 5 u - 17
= 5 x 5 - 17
= 25 - 17
= 8
Answer(s): 8
