- 5x1 =

- 16 |
After

1x1 =
1 u |
4 u - 16 |
The number of puffs at first is repeated. Make the number of puffs at first the same. LCM of 3 and 6 is 6.
Total number of pastries left
= 1 u + 4 u - 16
= 5 u - 16
5 u - 16 = -1
5 u = -1 + 16
5 u = 15
1 u = 15 ÷ 5 = 3
Number of more puffs than cupcakes that Elijah sold
= 5 u - 16
= 5 x 3 - 16
= 15 - 16
= -1
Answer(s): -1
