Imagine that Rudy does two productive activities: working out and changing lightbulbs. It takes Rudy 60 minutes to workout and 15 minutes to change a lightbulb. If he has 120 minutes (2 hours) two do these two activities, what is the equation for his production possibilities frontier (PPF) whereworking out is on the x-axisandchanging lightbulbs is on the y-axis?

1. y=2-0.25x
2. y=0.25-2x
3. y=8-4x
4. y=4-8x
