8 u - 11 |
The number of croissants at first is repeated. Make the number of croissants at first the same. LCM of 3 and 6 is 6.
Total number of pastries left
= 1 u + 8 u - 11
= 9 u - 11
9 u - 11 = 43
9 u = 43 + 11
9 u = 54
1 u = 54 ÷ 9 = 6
Number of pastries that Neave sold
= 5 u + 11
= 5 x 6 + 11
= 30 + 11
= 41
Answer(s): 41
