- 5x1 =

1x1 =
1 u |
10 u - 7 |
The number of puffs at first is repeated. Make the number of puffs at first the same. LCM of 3 and 6 is 6.
Total number of pastries left
= 1 u + 10 u - 7
= 11 u - 7
11 u - 7 = 59
11 u = 59 + 7
11 u = 66
1 u = 66 ÷ 11 = 6
Number of more puffs than scones that Brandon sold
= 5 u - 7
= 5 x 6 - 7
= 30 - 7
= 23
Answer(s): 23
