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 - 305
= 3 u - 305
3 u - 305 = 1
13 u
3 u - 1
13 u = 305
1
23 u = 305
1 u = 305 ÷ 1
23 = 183
Total number of muffins that Abi sold
= 5 u + 305
= 5 x 183 + 305
= 915 + 305
= 1220
Answer(s): 1220
