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 - 115
= 3 u - 115
3 u - 115 = 1
13 u
3 u - 1
13 u = 115
1
23 u = 115
1 u = 115 ÷ 1
23 = 69
Total number of croissants that Eva sold
= 5 u + 115
= 5 x 69 + 115
= 345 + 115
= 460
Answer(s): 460
