Total number of pennies that Harry had in the jar was 500. He sorted the pennies into 25 different stacks. If each stack had the same number of pennies, it means that the number of pennies in each stack would be the total number of pennies in the jar divided by the number of stacks. Therefore
If a person gets flat commission of $60 for every $200 of profit then for $1000 profit the commission would be $300. For $1500 the commission would be $450.
