The number of kaya croissants at first is repeated. Make the number of kaya croissants at first the same. LCM of 3 and 6 is 6.
Number of croissants left
= 1 u + 2 u - 238
= 3 u - 238
3 u - 238 = 1
35 u
3 u - 1
35 u = 238
1
25 u = 238
1 u = 238 ÷ 1
25 = 170
Total number of croissants that Dana sold
= 5 u + 238
= 5 x 170 + 238
= 850 + 238
= 1088
Answer(s): 1088
