Jade King · Answer 1

A) only if the new worker's daily wage is $120 or less

Explanation:

Since the new worker is expected to produce 12 speakers per day and each speaker sells for $10 each, the total additional income is $120. Since the market for speakers is perfectly competitive, then Mary should pay the worker a maximum wage equal to the additional income he provides. Off course if Mary pays a smaller wage she will earn more money.
