The number of chocolate croissants at first is repeated. Make the number of chocolate croissants at first the same. LCM of 3 and 6 is 6.
Number of croissants left
= 1 u + 2 u - 275
= 3 u - 275
3 u - 275 = 1
13 u
3 u - 1
13 u = 275
1
23 u = 275
1 u = 275 ÷ 1
23 = 165
Total number of croissants that Fiona sold
= 5 u + 275
= 5 x 165 + 275
= 825 + 275
= 1100
Answer(s): 1100
