Answer:
a. less than $350
Step-by-step explanation:
Since Randall needs lots of practice to earn his share of the band’s profit, which will amount to $350.
Gretchen gets distracted by Randall’s trumpet playing but she needs to get her writing done to earn $570 for her current article.
If Randall owns the right to play his music and Gretchen needs to hire a lawyer to help her reach an agreement with Randall, then the price that Gretchen is willing to pay the lawyer will be less than $350
The reason for the price being less than $350 is based on the simple logic that Gretchen could as well pay Randall his share of the band’s profit, which will amount to $350, for him to stop disturbing her while she writes, than to pay a lawyer that amount and still spend extra time engaging the lawyer.
