The number of kaya muffins at first is repeated. Make the number of kaya muffins at first the same. LCM of 3 and 6 is 6.
Number of muffins left
= 1 u + 2 u - 273
= 3 u - 273
3 u - 273 = 1
35 u
3 u - 1
35 u = 273
1
25 u = 273
1 u = 273 ÷ 1
25 = 195
Total number of muffins that Shannon sold
= 5 u + 273
= 5 x 195 + 273
= 975 + 273
= 1248
Answer(s): 1248
