Let's analyze the provided table to determine which buyers are willing to purchase the product at the given price.
The product's price is [tex]$90.
First, we need to compare each buyer's willingness to pay against the product's price.
- Calvin: Willingness to pay is $[/tex]150.00.
- Since [tex]$150.00 >= $[/tex]90.00, Calvin is willing to purchase the product.
- Sam: Willingness to pay is [tex]$135.00.
- Since $[/tex]135.00 >= [tex]$90.00, Sam is willing to purchase the product.
- Andrew: Willingness to pay is $[/tex]120.00.
- Since [tex]$120.00 >= $[/tex]90.00, Andrew is willing to purchase the product.
- Lori: Willingness to pay is [tex]$100.00.
- Since $[/tex]100.00 >= [tex]$90.00, Lori is willing to purchase the product.
Therefore, all four buyers (Calvin, Sam, Andrew, and Lori) are willing to purchase the product at the price of $[/tex]90.
Thus, the correct answer is:
d) Calvin, Sam, Andrew, and Lori
