The number of curry croissants at first is repeated. Make the number of curry croissants at first the same. LCM of 3 and 6 is 6.
Number of croissants left
= 1 u + 2 u - 105
= 3 u - 105
3 u - 105 = 1
35 u
3 u - 1
35 u = 105
1
25 u = 105
1 u = 105 ÷ 1
25 = 75
Total number of croissants that Nicole sold
= 5 u + 105
= 5 x 75 + 105
= 375 + 105
= 480
Answer(s): 480
