The number of egg puffs at first is repeated. Make the number of egg puffs at first the same. LCM of 3 and 6 is 6.
Number of puffs left
= 1 u + 2 u - 161
= 3 u - 161
3 u - 161 = 1
35 u
3 u - 1
35 u = 161
1
25 u = 161
1 u = 161 ÷ 1
25 = 115
Total number of puffs that Nicole sold
= 5 u + 161
= 5 x 115 + 161
= 575 + 161
= 736
Answer(s): 736
