If Harold isn't included, Harold would be sharing twizzlers with 20 friends.
But if it is including Harold, it would be 19 friends.
Step-by-step explanation:
The total number of Twittzlers = 80
let the number of friends he wants to share them with = y
Each friend gets = 4 twizzlers
The total number of Twittzlers/the number of friends = amount each friend gets
Solve for y to get number of friends:
The number of twizzlers Harold would have wasn't stated. If Harold isn't included, Harold would be sharing twizzlers with 20 friends.
But if it is including Harold, it would be 19 friends.
