$4500

Explanation:

We can calculate the total change in benefits by deducting the opportunity cost of spending the hours with your family by the annual salary.

Opportunity cost = $20/hour x 200 Additional hours

Opportunity cost = $4000

Total change in benefit = Annual salary - Opportunity cost

Total change in benefit  = $8500 - $4000

Total change in benefit  = $4500
