Answer: $25
Step-by-step explanation:
The Dictator game is used to measure just how much a person will act out of self interest especially give their surrounding. One person will be the dictator and the other a recipient who would be a stranger. The dictator will decide how much they are to give the recipient.
You live in a culture where you do not have to buy food and as this is a significant expense for humans, it means that you do not need much money. Regardless of this however, it has been shown that people would not give out the majority of their money which means that you would not give out 50% or above of the money.
As 50% is $25 here, that would be the correct option.
