People experiencing a medical emergency experience better outcomes if someone near them has first aid training and can immediately begin providing assistance. As a result, first aid training and certification is required for jobs working with the elderly and with children. First aid training also benefits the trained person’s friends and family. It even benefits strangers who live in the same community since it increases the chances that there is someone near them with first aid training when a medical emergency occurs.

a. Use a demand and supply graph to illustrate a hypothetical market for first aid training. 

b. Will this market result in a socially optimal level of first aid training, more than the socially optimal level of consumption of first aid training, or less than the socially optimal level of first aid training? 

c. Use your graph to label the socially optimal level of first aid training/certificates.
