I'm not sure how to interpret the information, as to who is to remain employed, fired, etc. The formula for MRP is change in TR / change in labor = P x MP.

Please advise thank you.

Zelda's MRP = $12 per hour while Yvonne's MRP = $8 per hour. The wage for both employees is $10. The firm should:

a. continue to employ both Yvonne and Zelda.

b. continue to employ Yvonne, but should fire Zelda.

c. continue to employ Zelda, but should fire Yvonne.

d. fire both Yvonne and Zelda.
