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 - 301
= 3 u - 301
3 u - 301 = 1
35 u
3 u - 1
35 u = 301
1
25 u = 301
1 u = 301 ÷ 1
25 = 215
Total number of buns that Tammy sold
= 5 u + 301
= 5 x 215 + 301
= 1075 + 301
= 1376
Answer(s): 1376
