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 - 260
= 3 u - 260
3 u - 260 = 1
13 u
3 u - 1
13 u = 260
1
23 u = 260
1 u = 260 ÷ 1
23 = 156
Total number of croissants that Emma sold
= 5 u + 260
= 5 x 156 + 260
= 780 + 260
= 1040
Answer(s): 1040
