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 - 265
= 3 u - 265
3 u - 265 = 1
13 u
3 u - 1
13 u = 265
1
23 u = 265
1 u = 265 ÷ 1
23 = 159
Total number of muffins that Wendy sold
= 5 u + 265
= 5 x 159 + 265
= 795 + 265
= 1060
Answer(s): 1060
