Answer:
A
Explanation:
Pat´s GDP formula is: Y= income-expenses.
At the beggining Pat was obtaining an annual product of $25,000
Y1=$40,000-$15,000=$25,000
But now, Pat gave up his income, which was $40,000. And also, now Pat does not have any expenses because he performs the child care ans the house cleaning. Then,
Y2=0
Y2-Y1= 0-$25,000=-$25,000. Pat´s decision decreased his annual product in $25,000
