The number of chicken muffins at first is repeated. Make the number of chicken muffins at first the same. LCM of 3 and 6 is 6.
Number of muffins left
= 1 u + 2 u - 385
= 3 u - 385
3 u - 385 = 1
13 u
3 u - 1
13 u = 385
1
23 u = 385
1 u = 385 ÷ 1
23 = 231
Total number of muffins that Elyse sold
= 5 u + 385
= 5 x 231 + 385
= 1155 + 385
= 1540
Answer(s): 1540
