The number of mushroom muffins at first is repeated. Make the number of mushroom muffins at first the same. LCM of 3 and 6 is 6.
Number of muffins left
= 1 u + 2 u - 295
= 3 u - 295
3 u - 295 = 1
13 u
3 u - 1
13 u = 295
1
23 u = 295
1 u = 295 ÷ 1
23 = 177
Total number of muffins that Pamela sold
= 5 u + 295
= 5 x 177 + 295
= 885 + 295
= 1180
Answer(s): 1180
