The number of chicken puffs at first is repeated. Make the number of chicken puffs at first the same. LCM of 3 and 6 is 6.
Number of puffs left
= 1 u + 2 u - 225
= 3 u - 225
3 u - 225 = 1
13 u
3 u - 1
13 u = 225
1
23 u = 225
1 u = 225 ÷ 1
23 = 135
Total number of puffs that Joelle sold
= 5 u + 225
= 5 x 135 + 225
= 675 + 225
= 900
Answer(s): 900
