B. Yvette and Carlos need to decide which one of them will take timeoff of work to complete tha rather urgent task of changing thebrakes on their car. Yvette is pretty good at car repairs; she canchange tha brakes in 30 minutes.
Carlos is somewhat slow; it takes him 5 hours to change the brakes. Yvette earns $160 per hous as a personal trainer, while Carlosearns $20 per hour as a clerk.

Keeping in mind that either Yvette or Carlos must take time offfrom work to change the brakes, who has the lowest opportunity costof ompleting the tak?
1. Yvette and Carlos face identical opportunity costs
2. Carlos
3. Yvette
