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 + 4 u - 8
= 5 u - 8
5 u - 8 = 37
5 u = 37 + 8
5 u = 45
1 u = 45 ÷ 5 = 9
Number of pastries that Zane sold
= 5 u + 8
= 5 x 9 + 8
= 45 + 8
= 53
Answer(s): 53
