The remaining number of stickers before Shannon bought another 76 stickers is repeated. Make the remaining number of stickers the same. LCM of 5 and 4 is 20.
Total number of stickers at first = 24 u
Number of stickers that Shannon had left and bought after that = 5 u + 76
24 u = 5 u + 76
24 u - 5 u = 76
19 u = 76
1 u = 76 ÷ 19 = 4
Total number of stickers at first
= 24 u
= 24 x 4
= 96
Answer(s): 96
