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 - 325
= 3 u - 325
3 u - 325 = 1
13 u
3 u - 1
13 u = 325
1
23 u = 325
1 u = 325 ÷ 1
23 = 195
Total number of puffs that Joelle sold
= 5 u + 325
= 5 x 195 + 325
= 975 + 325
= 1300
Answer(s): 1300
