Final answer:
The customer's lifetime value is C. $1,200.
Step-by-step explanation:
The customer's lifetime value can be calculated by multiplying the average customer revenue by the profit margin and the number of years loyal. First, calculate the profit from each customer:
$4,000 (average customer revenue) x 10% (profit margin) = $400
Then, calculate the total profit over the customer's lifetime:
$400 (profit per customer) x 3 (number of years loyal) = $1,200
Therefore, the customer's lifetime value is $1,200.
