The number of curry muffins at first is repeated. Make the number of curry muffins at first the same. LCM of 3 and 6 is 6.
Number of muffins left
= 1 u + 2 u - 126
= 3 u - 126
3 u - 126 = 1
35 u
3 u - 1
35 u = 126
1
25 u = 126
1 u = 126 ÷ 1
25 = 90
Total number of muffins that Elyse sold
= 5 u + 126
= 5 x 90 + 126
= 450 + 126
= 576
Answer(s): 576
