The number of chicken buns at first is repeated. Make the number of chicken buns at first the same. LCM of 3 and 6 is 6.
Number of buns left
= 1 u + 2 u - 203
= 3 u - 203
3 u - 203 = 1
35 u
3 u - 1
35 u = 203
1
25 u = 203
1 u = 203 ÷ 1
25 = 145
Total number of buns that Kimberly sold
= 5 u + 203
= 5 x 145 + 203
= 725 + 203
= 928
Answer(s): 928
