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 - 310
= 3 u - 310
3 u - 310 = 1
13 u
3 u - 1
13 u = 310
1
23 u = 310
1 u = 310 ÷ 1
23 = 186
Total number of croissants that Victoria sold
= 5 u + 310
= 5 x 186 + 310
= 930 + 310
= 1240
Answer(s): 1240
