The number of chocolate muffins at first is repeated. Make the number of chocolate muffins at first the same. LCM of 3 and 6 is 6.
Number of muffins left
= 1 u + 2 u - 350
= 3 u - 350
3 u - 350 = 1
35 u
3 u - 1
35 u = 350
1
25 u = 350
1 u = 350 ÷ 1
25 = 250
Total number of muffins that Kylie sold
= 5 u + 350
= 5 x 250 + 350
= 1250 + 350
= 1600
Answer(s): 1600
